Is it just me?

I have no idea why i feel that recently but whenever i saw x takes pic with girl . I felt so insecure. i mean if it was just a normal pic i wouldnt mind but they are like so close . I mean i know the girl already have a bf but i dont know why is it bothering me so much. If you were to be in my shoes, won't you feel the same too? And hmm recently i have been feeling very insecure about everything. Insecure about how i looked , insecure about just being me. Haish... i dont know anymore
