I shouldn't be here, I really don't fit in at all?

This world just makes me cry, I feel sad all the time but I always put on a mask when I'm around my friends, they don't understand me and I just feel as if they use me and forget me. Nobody understands how I feel, I just don't feel happy anymore. I'm pig ugly, and that's all people care about apart from money these days. I just feel so lost, everything in this world just disagrees with me. I try to be happy but after two days I'll be crying again because of the stupidest thing and then I'll just write down everything that makes me sad and I cry harder. I'm only 16 and nothing traumatizing has ever happened to me but I just feel so wrong, god hates me for being gay and I can't feel him around me anywhere, he disappeared like all my good friends I've ever had.
