Recovering from anorexia

I've struggled with depression, anxiety, anorexia and bulimia for about 4 years now. (I just turned 18) I've been on medication, (which never helped), been through counseling (that never helped either). But I have gained some weight! I am 5'2 and started at 78 pounds and now I'm at 97. I stopped bulimia about 6 months ago and haven't started again, so I have made a lot of improvement! 

But I'm still not happy with my body. Every time I meet someone, they tell me how disgustingly skinny I am, or tell me I need to eat more. It gets really annoying and it kinda hurts my feelings because I feel like I've been doing really good. I still want to gain about 10 pounds, I just have a really fast metabolism so it's really hard for me to gain weight. I just want to have a nice body for summer, and I don't want people to tell me that I'm too small, it doesn't help me at all. Any tips or advice on how to gain weight & also how to handle comments like that? I never know what to say, and it really just comes off as rude. 

Please no negative comments or "I wish I had that problem" because this is a sensitive topic and I don't think anorexia gets enough attention, people don't take it seriously. 

Thanks so much! 💋
