extreme baby fever help

hey, I need help. I have had very bad baby fever for about 2 months. it’s starting to get so bad that every time I remember I am not pregnant and can’t get pregnant, I deep pain in my heart area. I hate social media these days because it seems like everyone is pregnant. me and my boyfriend have talked many many times about it and him and I both want a baby so bad. I have helped raised my sisters to the point where one called me mum. I don’t know what to do. I’m such a mess.
