Am i a bad person?

I love my family and friends. I am so bless to have them but I can't help but feel jealous when they come out pregnant. I would never want anything bad to happen to them at all or their babies. It is just hard when I have been trying for three years.....I want to not be sad but at the same time I can't help it.....I am going to the doctors to find out why but in a way I am really scared I have had chances to go but I end up backing out because I panic. I love my husband so if he is the reason I can't get pregnant does not mean I'll leave I guess in my heart if I find out why I haven't then it will make me feel better but at the same time it will brake me! All I ask is please pray for me....I feel lost and my hope for a baby is fating.....has this happened to you? How did u handle it.......also for the past 3 year my body has changed so much it is unreal!
