I want to recover!!!!?

I want to know how I can not feel bad about gaining weight, since 3 days ago I have gained 2 pounds and already feel like im really fat :/ I can't keep living like this because this is not a life I'm living its a nightmare! I weigh myself around 4-8 times a day to check my weight and I hardly eat but when I do I am very fussy regarding what I eat, I am 18 years old and have had problems with food for around 4 years now due to bullying at Highschool but I was overweight, I was diagnosed in january with anorexia :/ really dont know what to do :/ is there any hope! I am not a strong person :/ I also currently see 2 counsellors which doesn't help also I have been in hospital twice since January due to complications such as dehydration and cheat pains :/ I am only 18 and I will be lucky to reach my 19th birthday
