terrible friend

I'm a little sad tonight. I came home from work, very tired and angry because of the bloody bus. But I know that it isn't the bus or the usual weirdos you see there every day. It's because I'm unhappy these days and a friend of mine is so happy I almost can't bare it. I know it is a terrible thing to say about a friend, but I can't help feeling like sh*** every time she talks about her happy life. Ugh, I'm a terrible person, I know, but I had to tell someone, and who's better than the void out there called internet? Maybe I'm a bad friend, I don't know, but shouldn't I be the lucky one and not always everyone else I know? Who is going to listen to me?
