Aww I am sorry to hear about your break up
I kinda know how you feel. I was with my boyfriend for over 5 years and we broke up in February... I was devastated. But I had to try and accept it but I didn't actually start feeling 'ok' about it until about a few weeks ago, so about 7 months after we broke up. I still miss him though - not sure why, because he was a total pig!

and I am not just saying that, I am being totally serious. I had such low confidence and let him bully me and I believed I loved him and he would change.
Anyway, I am not interested in having a relationship right now, I am happy being single. I'm not so sure I will want to remain single for the next 2-3 years though! So too, like you, worry what guys will think of me in a brace. I'm 24 but have experienced alot of horrid things in my life and it's kinda made me 'tough' in some ways (and not in others!) and not care so much what others think (that's why I don't have any issue being an adult in metal braces), so even though a part inside of me worries that guys wont like my braces, another part of me is like "well, who cares... their loss!"

. If they don't like it then they can shove it where the sun doesn't shine. Someone who wants to judge me on my braces/appearance aren't the type of guy I want to date anyway. I had enough of my ex picking on me and judging me ALL the time, I do not want another relationship like that! I am stronger now and will not let another man put me down.
Rant over, sorry!
Break ups are never easy in my opinion. But try to be strong and keep busy! I think keeping busy is the best thing, and time is definitely a healer x
