Anxiety....

My husband and I have been trying for a year and a half and I'm o my 3rd cycle of clomid 50mg but i feel like I'm losing my mind. But does anyone else get angry when others announce there pregnancy? Angry then pure sadness that takes over. And then a million questions like why not me? What makes them so special.... I don't want to feel like this and it makes me more upset that I do. I want to be happy for people when they announce pregnancy.
