I have full scale conversations with myself…Is this abnormal?

I have done this since I could talk as a tiny child,I will discuss situations that have occurred as if I am talking to some one else!!I could never stop now because I find it quite comforting,I have had quite a diificult life,but even if I hadn’t I think I would still do this,sometimes I will laugh at something I have remembered.
I have social anxiety & am not generally comfortable with other people & I find that I have the best conversations with myself,I have lived alone since I was 17 & will sometimes spend hours just chatting away….to myself!!I will talk about my plans,my future,my regrets,how much I hate certain people,anything & everything really,I will also tell myself what I am going to say to people!!
I know that everyone talks to themselves to a degree,i.e,”oh crap,where did I put that?”
But after reading what I do,do you think this is normal?It doesn’t really matter because after 27 years of doing this I’m not going to stop am I?lol

It’s not that weird. I talk to myself sometimes too. We are our own great listeners.
