Well, you're right I do have some kind of form of DID but, I stopped talking about it around here because there were some "experts" hanging around who disagreed because their perceptions were different from my own.
Well, as far as the evil personality goes, he likes to tell me that I'm an idiot and a nobody and all the other kind of crap that cruel people enjoy saying to others to try to bring them down. He also thinks me to be and even calls me a weakling. Weakling, coward, moron, dumbass, pathetic and etc.
I really don't recall anyone ever talking to me like that when I was a kid or even a teen but, I did get bullied a lot, called names and get accused of being really dumb which wasn't true then and isn't true now but, during spells of hyper activity or when I'm on a bipolar high I do tend to get on others nerves with my antics and silly attitude.
I think a lot of my dark alter's insults were picked up from other fictional villains and tyrants and he certainly is as arrogant as many of them if not more so. He's highly delusional as well. More so than any of my other alters.
When he takes control I am at his mercy -not that he has much- and have to wait for him to tire out and go away on his own. Afterward I feel drained of energy. And it's like I've said before. If it isn't DID then, demonic possession is the only other thing that it could be.
While I'm no expert on demons I do have a little experience with demonic activity one might say so, I figure I know what I'm talking about.
If anyone disagrees I would like to hear their opininions.
