Single mom

So I am pregnant and I already have my son I'm expecting a little girl in October it's driving me crazy and I feel so resentful because I have never been with anyone while pregnant they both have the same father but the relationship will never work so it's just me I really would love nothing more than to have someone to cuddle with at night just having the support of someone else would be amazing since I don't know what that looks like I'm at a loss
