Has anyone else felt this way....?

I was pregnant 2 years ago and had a miscarry at 10weeks it was a very very sad time for me and i havent be able to fall pregnant since. But now my best friend has fallen pregnant and im very very jealous of her. 1. because she has had 2 abortions before just because she didnt want the babies and im very against abortions and 2. she is with her boyfriend of 1 year and he has been cheating on her and they were just about to break up... Has anyone else been so jealous and upset beacuse everyone around you is pregnant and your not and you lost your bub :'( How do I get over this feeling I hate feeling like this :(
