Lonely and venting

Hello all, I'm a young mom who's 20 years old. I am 3 months into the pregnancy. Lately I had a lot of problems in my family to the point I don't know who to turn to and it makes me feel lonely. My partner and I are great and he's been supporting me most of the time but I don't see him everyday because we don't live together and he is doing his own thing too. The point is, I feel so alone and lonely because I lost family ( distant and no longer talk anymore) and friends? I don't have any but 2 close ones. I just want someone to talk to. I am trying to find a support group or a group of moms who may feel the same way I feel. I work and it has been a distraction but it's just hard coping with this feeling. Sometimes I ask myself am I making the right decision to moving on with the pregnancy because I have no support on my side and feel like I don't have anyone to turn to with like my problems or what I am going through personally. My sister and those who I would talk to turned their back against me which I don't understand why . I've also been stressed out about my job because they treat me as if I'm not pregnant and don't have appointments to attend and I feel like they care about their company more than me. I work with kids so I'm risking me and my baby's life by working going home to home for sitting. I'm not sure if I should continue to work or not so that's been on my mind as well. I just wanted to share this because I have no one to talk to and my partner says he understand but I don't think so because he's not in my shoes or carrying a baby and having such thoughts go through his head. But who ever reads this thank you for hearing me out.
