Some are negative because others put them down, outer forces affect their opinions of themselves. I'm kind of the opposite, nobody hurts myself better than I do! I am always negative, always hating on myself for everything I do. I criticize everything I do, I am always disappointed in myself, because I feel everything I do is never good enough.
I spend a lot of time in my head, sometimes it can be a good thing but most the time it drives me to insanity. I enjoy being alone, being alone does not make me lonely, but sometimes if I am alone to long my mind kinda finds itself in dark places.
I am always trying to help others out, I generally put others before myself, but at some point I should start helping myself.
I'll stop here.
