Friends disappearing

I’m pregnant with my first. My SO got a second job to help with our medical bills so he is gone all the time. I’m constantly alone and can’t help but feel sorry for myself. I feel all my friends are just out partying or can’t be bothered to check on me or go to dinner or ask me to hang out anymore. Feel like I’m not having any fun doing baby stuff because I’m always doing it alone. I just feel so low. Anyone else going through this too?
