Crazy or Not...

What happens when you start to enjoy talking to yourself? in the past when I have been more alone then normal I tend to talk more out loud... but what I can't figure is whether or not I'm going crazy or I am just getting use to my own mind... I am an artist.. so I know I have more crazy then maybe some... I am also the youngest makes me observant. I started talking to myself.. at the time my brother who I live with has been grumpy and honestly I don't think he even knows when I'm home anymore.. so I talk and I talk... then I realized that I really didn't mind my conversations with myself. Now maybe one day someone will tell me I'm insane or just adjusting to knowing my own mind.
I found that I don't want to be around people only because of how often trust has been broken. but that is alright for now.. after all I'm getting good at talking to the person in my head that is never there anyway.
