TTC Jealousy

So my husband and I are trying to conceive baby #1. As I'm sure a lot of you can sympathize with, it is all I could ever want right now to get a positive pregnancy reading. One of my best friends is pregnant with her second unplanned child. Her and her boyfriend don't have the most stable relationship and so her reaction to her pregnancy hasn't been overly excited. I was ok with it and excited for her. Well today my other best friend tells me she's pregnant too. Again, not the most stable relationship and not bursting with excitement. I am just finding it so hard to be excited for them when they aren't excited and that is something I want so badly. I feel like a horrible person for feeling jealous. I just can't help it. Anyone else dealing with this? Any tips on ways to minimize the bump jealousy??
