Hey, I'm so sorry to read that about you. It's not your fault your mother is clearly either selfish or avoiding your problems thinking that might make them go away. My boyfriend does that and it almost makes it worse. I'm 25 now, but when I was 15 I wouldn't listen to anyone, so congrats on being on the forum and trying to get help. After looking back at it all, if I could do it again, I would try and measure my self worth in the amount of relationships I built and maintained with people then trying to measure my self worth with money, body image, career, ect. Eff all that and go create a family of friends of your own.
