Am I normal?

So I’m a stay at home mom to two young kids and I don’t really have many people to talk to about my problems. Sometimes I find myself talking to myself to try to like sort things out and sort out problems. Its not like I actually think I’m talking to someone like I know I’m talking to myself. Is this normal? Or do like I need to see someone? I’m just scared because after my second baby I’ve been doing it a lot. I just feel alone…
