NO, it's not normal. You are the child. Someone a few days ago posted about a pyramid of needs being met, and you should see if you can find that. It might be enlightening to you, because it sure was to me. You're parents are not meeting your basic needs, and certainly not your sibling's basic needs.
Hmmm. Okay. Not sure about sharing this story, because it's potentially triggering but it does fit. I should probably say that there's neglect triggers all over this one, and I'm probably responsible for some of it. At least, I accept responsibility for it.
My mother opened her 'dream business' (it was a nightmare, not a daydream, but she's gaslit herself and everyone else into thinking otherwise) when my youngest sister was a toddler. I was around...12? Which made my brother 14. So, a 14 year old boy was left in charge of his three younger sisters who were 12, 10, and 2.
The first thing he did when left home alone with us was go to his room, lock the door, turn up his music and play video games. I told my parents this, but my Dad was working (unavailable, he works government) and Nmom told me I was being a tattletail. So, I was left in charge of my sisters every day of the week except Sunday, from before they woke up until after they went to bed. Some days I didn't see my parents at all because they didn't come home until after I had gone to bed.
I couldn't cook. I also didn't know how to do laundry, or clean the house, or many of those things, but I was pretty resourceful and figured it out. My sister wasn't really potty-trained either, but we at least managed to bring that up to speed relatively quickly. My Nmom would do this sigh like I was intentionally wasting her time if I told her that I was having trouble with something, so I did my best not to bother her with much and tried to do everything myself. My brother came home from school every day and went into his room. I don't know if he would have noticed if the house burned down. I used to ask him for help and he would tell me he was busy because high school was harder than middle school (lies, he was playing video games).
Pretty inevitably, my 10 year old sister became resentful that I was in charge and developed an eating disorder. I could only cook maybe three things, so it was pretty reasonable. I hated my cooking too. At the same time, I didn't know how to handle seeing my sister literally waste away to skin and bone in front of me and that oh god she's dying feeling turned into rage so we spent a lot of time screaming at eachother. It didn't help the stress of having a whole household depend on me either.
My baby sister didn't understand what was going on. She never saw my parents, and I took care of her, so in her eyes I became mom. She started calling me Mom. I tried explaining why that wasn't correct but she was, and still is, a stubborn person so it didn't go very far. I soon just accepted it. She became clingy. She was always underfoot, and cried if I didn't pay constant attention to her.
Although I had been pretty diligent about making sure that my sisters did their schoolwork (I didn't know wtf to do with a toddler, so she had homework too. She learned to read at a ridiculously early age becuase I was so clueless), someone finally noticed my sisters eating disorder. A parent-teacher conference later and I became responsible for my sisters doctor appointments. I would walk my sister into the appointments and smile and tell just the right lie so that they would believe that a parent was waiting outside for us, we had to go run errands and would be right back. I would fake the paperwork that I didn't understand.
My mother's business starting getting worse (embezzlement), so instead of getting my Sunday breaks, my Dad starting going on long business trips because they had better pay. He didn't want to ruin her dream. My mother started dumping more chores/expectations on me. At this point I was raising two children (one of whom was seriously mentally ill), maintaining a household of six people, as well as trying to keep my head above water with my own school work because I was trying not to draw attention to the fact that I wasn't doing well at home. I didn't have time to sleep because there was always something I needed to be doing. I remember one time the hot water heater went out and I couldn't call anyone to fix it because they never would have taken an appointment from a child. I googled things and fixed it myself. Years later, I learned I should have turned off the electricity first. I could have burned myself alive, sticking my hands into boiling water. Sheer luck that I didn't.
Everything sort of came to a head one day when my sister refused to eat and I started begging her to because I knew she hadn't eaten breakfast or lunch that day. She physically attacked me, to the point that I looked like I was mauled by an animal but at that point in our lives we were physically pretty even (her from malnutrition, me from exhaustion). I realized that my baby sister was in danger if I didn't get her removed from the situation, and I eventually managed to trap my sister in a room and lock the door from the outside. While that was happening, I had begged my baby sister to hide in the closet with her toys/stuffed animals so that she was safe because I didn't want her to get hurt. As soon as the door locked, my sister became enraged to the point that she started battering her own body against the door. There were these sort of sickly-wet crunching noises every time she made contact with the door, because she kept throwing herself against it over and over. It was so out of control at that point, and I was so overwhelmed. I didn't know what to do anymore.
I called both of my parents cell phones and told them what had happened and that I couldn't handle the situation and they needed to get home immediately. My father was on a business trip, but it was within-state.
And then I left the house, and started walking. It was raining, sort of drizzly-ish, and cold because it was autumn, and I just kept walking.
Early the next morning, a neighbor that was part of an organized search-and-rescue found me and brought me to a police officer. I was treated for symptoms of shock and early pneumonia, plus the infection from where my sister had attacked me and I had bled.
My dad had apparently gotten the message fairly quick and forced my mother to go home immediately (closing the business, gasp!) where they were able to help my two sisters. My brother was in his room with his headphones in, entirely unaware of the situation, as he had been for months (almost a year) at that point.
The "official" story, as far as I know, that was given to the police officers was that I 'forgot' the 'emergency procedures' that we 'practiced' and 'didn't go to the neighbors for help' like I was supposed to. That it was a one-off. They used my sister's medical records to show that she was in treatment and everyone was sympathetic to them. I was taken to a councilor, who talked to my mother immediately after my first session. She had told me that everything was confidential. I saw her talk to my mother, I told the both of them that they had lied to me and I wasn't coming back again.
My mother's solution was to make me an employee at her business.
