I'm highly mentally unstable

My boyfriend made a comment about a year ago that I haven't been able to forget it goes a little like this "before being in a relationship you were not my type (physically speaking) but not I can't stop looking at you" I cried for days trying to forget about it, I wonder why I wasn't enough for him. I looked at his previous crushes and they were all beautiful, nothing like me. It makes me feel like he just adjusted to me to have a relationship. I'm so sad and angry I don't feel enough. I've always had issues with my body.

Update: wow guys some of your comments have been really helpful, thanks, other not so much. I've had low self esteem since I was 11. I've had depression and I'm seeing a psychiatrist, psychologist and neurologist because I attempted suicide and this was one of the comments that made me feel like I was never going to be enough for anyone. Some of you might not see it that way and that's good, I wish I could be a little more positive about the situation but at that time I couldn't. I guess the only thing I wanted was to feel appreciated in every aspect and by his words I felt the opposite. Sorry if I upset some people by this it's just my point of view
