Has anyone grown up with just their mom and a pet cat?

I’m about to have a baby. I have no family other than my mom and she’s about to move. The father isn’t going to be involved. Has anyone grew up in that environment? I plan to be the best mother I can be and go all out for my child so it doesn’t feel so lonely. I just wonder if I’ll be good enough. And no friendships either. A lot of them I outgrew and they were toxic. I need to make new ones. Can someone give me advice on his? No rude comments please, I’m going through enough.
