Stop talking to myself

Is it really abnormal? Sometimes I think aloud and my mouth moves but there’s really no sound coming out, which is good. But my aunt saw me today moving my lips and she said she always catches me doing that. And I didn’t know, maybe it’s subconscious. But now i’m aware of it and I want to stop it. I don’t want people to think I’m crazy… even though I’m not.

I know crazy is when you hear voices in your head. I’m just voicing out my thoughts and sometimes I just don’t want anybody hearing what I want to say. So I’m just keeping it to myself by doing that.

I don’t know how to completely stop this but I will try to be more conscious when around people.
