Will my metabolism get back to normal after and ED?!

Sorry this is my first post but anyway, I was blessed with a super fast metabolism and a slim body but that was not enough. I suffered a bout anorexia for 5 months before I binged then couldn't stop binging everyday for 2 months. I'm slowly getting normal eating habits but that's not possible if I don't even get hungry(or full)!! after about 2 months wiyth my Ed it'd take me 4 days to get hungry after eating (I would not eat all that time)(but the remaining months I was hungry all the time). these days it takes me at least 12 hours of not eating before I get hungry. I do eat 3 meals a day like normal people but I really feel I'm putting it on as weight because its not used up quick. I've gained twice as much as I've lost and still gaining!! I just want to stop gaining and be normal (eat whrn hungry, stop when full)and have my metabolism back!! is it possible? also I'm a teenager if that helps(sorry for coming here)
