Unsure about my baby

I’m 22+5 weeks. When I was with the child’s father at the beginning of my pregnant I wanted this child with everything I had and now I’m not with him I’m unsure if I can do this alone. I keep having different emotions. One day I want my child and the next I don’t, I even want to give him up for adoption when he’s here. But tomorrow im going to want him.

Is this completely normal? I’m just scared that I wont be able to do it alone tbh.
