Eating problems

So.. idk if it's technically an eating disorder but... I used to be anorexic, I haven't been able to gain any weight since I stopped and that's bc I still have trouble eating a lot. I hate eating in front of people, and I don't like eating if nobody else is. So if im at my boyfriend's house I wait for him to get his food before I start eating. It makes me feel more comfortable about it. I'm super insecure. 5'4, 16 years old, 105 lbs. These are the most recent pictures of me. I want to be skinnier
