Anyone else feeling really alone ?

I’ve been feeling very alone lately. I feel like I have no one to talk to that has anything in common with me. I’ve parted ways with some friends and the other ones are either not in relationships or not pregnant, they just won’t get anything I’m feeling. My husband tries so hard to be as supportive as he can but he just doesn’t get what I’m feeling and the changes my body is going through. I wish I had someone to chat with about pregnancy and marriage or when I’m feeling down. I don’t even have work friends, I feel so left out there. I just don’t feel like I have someone that understands me and I kind of feel like a failure in life. I want my future child to be proud of his mom. I don’t feel proud of me
