Mom guilt for wanting another baby

I suffer from depression and anxiety, I’ve spent the past year doing counselling and seeing a psychiatrist every week since April, lately all I can think about is having another baby.. I have two sons age 6 and 2, they are my world but I can’t help my jealousy when I see people having babies and I’m wishing that was me. I know this isn’t a good time to have another baby only because I need to get my mental health in order first.. does anyone else get jealous when they see others having babies? I hate that I get this way but I can’t help my feelings
