hi. my name is cat and I live in te US. listen I think you look beautiful!!!! I have the same problem. I have a big ugly brown birthmark on my stomach and it drives me insane because I am ashamed of it and can't wear a bikini. I have tried putting makup on and band aids but they don't work. earlier today (ik this sounds stupid) but I put on one of my old bikinis and I told myself in the mirror that I was beautiful. it really helped and I am planning on buying a bikini later this week. ik it's hard being a teenage go with a birthmark but just shun all the loser that tell you it's ugly. I'm gunna face my fear so I hope you realize that yor gorgouse and it's not that big of a deal so learn to love it.
