My reputation always changes and for some reason, it causes me to lose friends?

Some days I am hilarious, some days I'm serious and very melodramatic, and some days I just weird. When I first meet people, they usually see my GREAT sense of humor side because I can be hilarious, especially on first impressions. But my comedy isn't consistent and if I keep it up, then I usually just make a full of myself.Then sometimes weirdness kicks in and I act like I'm high or something because I get incredibly hyper and often perverse and inappropriate. I never keep the same image and each day I often change the way I act. I cannot really be myself, well unless you mean being who I am day to day, but my mind changes so much that my image changes as I go to and so I usually only keep friends up to around a week. I'm antisocial and I am home schooled and I never get out or around people. I stay on the computer so I don't really have a specific personality I go by. But I don't really understand how my mood fluctuations could cause me to loose friends. What do you think?
