I am hurt

Today was my birthday and trust me when I say this, All those people who i thought were my friend didn't even post about me or wished me ,until very late . I usually don't let these things bother me but damn this actually hurts because of the fact that I was always the perfect friend for them and I was always there for them. I know they might be busy or they might had some work to do that I'm not aware of ,but I just can't help but feel that they don't care about me ,they only want my assistance when they need to vent or when they need help, i also feel like they don't want to post about me because I'm ugly? idk I'm getting so many thoughts about this ,I'm trying not to think about it but I just can't stop . I know it may sound stupid but yeah I can't belive a 22 year old dude like me is venting about friends who didn't wish me on my birthday.
