I don't feel happy

Haveing a baby is the only thing I've wanted for a long time.i didn't think it was ever going to happen because I have stage 4 endometriosis.so when it happened I was so happy but I hate working because I'm with people that are jealous and it just feels like I can't enjoy being happy for myself. I would be so happy for them if they got pregnant. I just want to be happy and not feel stressed and sad anymore. :-(
