back again

so here we go again. i have not been on this site for almost a year and a half for i have been better from my problem. so i thought. now i am having more problems then ever and i cant stop making myself throw up again and nto wanting to eat and obsessing over food. i cant go through this again! not again. im scared and dont want to end up like how i used to be. i dont know what to do or where to go and i have absolutly nobody to talk to anymore,
