I'm not sure if this is a mental illness or not. It could be a symptom of my depression, but I've always talked to myself a lot.

This only happens when I'm alone. I make up conversations/arguments with other people who I may or may not know. I'm pretty sure this isn't schizoprenia or anything because I'm aware that the people aren't with me, and I'm not hearing voices in my head other than my own.

idk, this is probably a stupid post, but I was just wondering
