I have had this problem since I was a young child I'm 19 years old and my food choice is even more limited now I eat a select few things which are all unhealthy like pizza, chicken tenders, fries,etc. I will eat fruit and salad but not a lot of vegetables and have struggled with weight my whole life. I'm very anti social/introverted. I'm not sure if it just goes along with it or not. But my family always gave me so much hell for it as a child trying to force me to try things and they didn't understand it literally would make me gag/throw up getting near the food. At any restaurant I always get chicken tenders which is why I avoid going out to eat with people because it seems childish to order it. I'm just glad I'm not the only one!
