Eating disorder help?

Hi, I'm 18, and I have anorexia nervosa an have dealt with it since I was 15, I was bullied at school because I was fat so I took drastic measures, I urge you not to start, I am trying to recover and it is the hardest thing I have ever had to do in my 18years on this earth, I have been in hospital 3 times over the last 2 months and let me tell you what it's like, I wasn't aloud out of my bed, wasn't aloud my phone or laptop, no communication with my friends and family for a week the first time and 2 weeks and 5days the second time, eating disorders kill and I know that as I continue to struggle and have serious health issues relating to my anorexia, I have heart problems which have to be monitored. I dont think I'm thin but everyone around me says I look like a walking skeleton, I hate making everyone so worried and scared, I am currently thinking about entering a rehab program for my eating disorder :) please get help if you need it :)
