I had it when I was 13-14 then if transitioned into a severe cycle of binging and purging. From my experience (everyone's different) I felt lethargic and depressed, I'd go a few days without eating and become gradually more angry and depressed. I isolated myself from my friends who in turn I lost (am now 20 and don't have those friends in my life) I didn't eat in front of people, I wouldn't go out if I had eaten anything I considered "unhealthy" that day. So for example if I ate a bowl of white rice I wouldn't go out or hangout with anyone. I watched videos on youtube obsessively of other anorexic girls. There's one memory I hate thinking about, I was severely underweight for my bmi and my mom mentioned how skinny I had gotten I told her I was hungry and willing to eat and she said she only had enough money to buy my brother food. That was the same day I became bulimic. Luckily because of my mom and dad they found out how bad it was and took me to amazing counseling and therapy at Stanford and I recovered. I still have some issues with my body but all in all through therapy and going vegan I've been the healthiest I have in several years. If it wasn't for my mom caring so much I'd probably still be there.
