Is it normal to talk to myself when I'm mad/upset?

I do this exact thing all the time. Always made me feel not normal, and I hardly ever do it and I don't even feel much better afterwards compared to if I did nothing, but it just feels like a natural thing. I can do it for hours, and sometimes I type what I say on my laptop/computer/iPod or whatever is around, then password protect it and keep it, but I almost never look at it.
