I feel so alone. Ladies, can you lend an ear to hear me out?

I am also going through a crazy crappy time in my life and would appreciate some companionship... From males or females but I would love some girl friends!

I am struggling through an addiction to pain pills, my father was diagnosed with leukemia 3 months ago, I am depressed, my 16 year old dog's health is declining fast and we will provably have to put him down soon, I am saving up to get a full dental reconstruction and am currently dealing with some terrible nerve pain from cavities(I am a recovered bulimic and repeated pulling wore out my tooth enamel and totally wrecked my mouth.. It sucks), my job is in jeopardy even though I love it and give it my all and it pays decently, my car is falling apart. My best friend (who I have been in love with for about 4 year now and have been friends with for 10+) is dating a girl who is almost 10 years younger than him and who is cheating on him and using him for financial stability ... He talks to me most days but he can only sneakily hang out with me behind her back and it hurts and sucks.

All of this shit amongst a billion other things are shoving me into a deep depression and I honestly contemplate suicide multiple times a day. I don't think I could/would ever go through with it but I know it's not good or right to be feeling like this. I only have...4 or 5 friends. One of them is a work friend that I am pretty sure just wants to get into my pants, one is my best male friend of 10+ years who I am in love with but he's in a terrible relationship and we have to sneak being friends, one is my baby sister who I consider my absolute best friend and favorite/most cared about person in this entire universe. She is going through and addiction and it's changing her. Also she has a controlling, manipulative, emotionally/mentally abusive boyfriend who is a fucking scumbag junkie loser who is sneakily living in my house (my parents let him live here for a year and a half, free of charge, and they finally got fed up when he was eating all of our food, stealing my father's tv, tools, etc because he was in the hospital undergoing chemotherapy and was neutropenic and almost died from a blood infection, then lost his job and a bunch of other shit) against my parents wishes (he literally hides in my sister's room all day and just comes in and out my sister's window, sneaks food, they just get high and watch tv) and my parents are super non confrontational and just ignore their problems hoping they will go away. They raised me to be the same way and I am trying my best to change such habits and face any problems head on life.
