Starving myself

I weight 184 pounds, at 15. I’m not happy about it and lately my anxiety about it has gotten really high. I started to starve myself. My friends force me to eat and then after I feel terrible about myself, I’m trying to workout at least once a day, and I’m not sure what to do or who to talk to. Whenever I try and talk to one of my friends they compare it to them and say once I get to there weight then I can start to complain. I’m not complaining I’m trying to get help, I want to be 140 pounds by then end of June. I’m staving myself, I don’t know who to talk to anymore. :(
