I know that's so hard. It wasn't that I wasn't happy if a friend got pg, but I was so sad for myself and it made me feel like it would never happen to me.

Is your friend aware of what you're going through? It's hard to know how people will react. Perhaps you can talk to her and try to explain that it's not that you're unhappy for her but you're hurting so much for yourself that it's hard for you right now. Don't feel bad for grieving for yourself. Sometimes there are no easy answers as to how to react to this; you just need to feel your way through it and do the best that you can.
