<human>: 3 days ago I was at a party with my boyfriends friends and himself. I was standing around this bonfire type place and he left to go talk to someone he knew. I have been with my BF for a year and a half 

I was standing their with his friends and out of the blue they started talking about his ex girlfriends. One of his friends made the comment " I'm surprised he is dating you, he normally goes out with girls with larger chest's". 

I am flat chested and I have always been super self concious. I kinda walked away at this point, I felt embarrassed and it has put alot of thoughts into my head. Like is he going to leave me because I have no boobs, is he annoyed by it. 

Last night we were in his room on his bed watching a movie, and I could not even cuddle with him. I felt that it would annoy him I don't have big boobs, and he does not like it. 

He kept asking what was wrong, and I did not want to bring it up because I thought it would lead to a fight or him telling me he does not like the  way I look. So I just told him I did not feel well, which I do I feel physically sick thinking about it. 

I don't even need to wear a bra, I can wear an A cup if I stuff it a little bit. I have thought about doing that, but it's like what's the point. 

Am I overreacting to this and thinking to much into it?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My BF friends have made me feel self conscious about my breast size and now I am panicking that he does not find me attractive.
