I Don't Think I'm Pretty But Others Do...

I love photography . So I take a lot of pictures of myself. I edit them but not that often and post them on Facebook. I can honestly say that I think I look pretty in pictures but when I look in the mirror I just want to cry. I hate the way I look. I look very weird from the side and my nose is rather big. And I always wonder... why do people always say I'm pretty? If I were pretty I think more people would like me but instead I only have 3 friends. I never feel pretty enough. My own family members call me ugly and fat. Nobody realizes how insecure I really am...
