just another part of the fear of losing control or doing something that you don't have total control over or doing something weird in front of others. i'm not trying to belittle the awful feeling of it, but that is the essence of what it boils down to.
maybe try asking yourself: why do I fear THIS? Why do I fear that i am delusional, instead of fearing something like cancer instead?
I think I had those fears because I cared a little too MUCH what people thought, I had to appear an exact way around people and not do anything stupid or to let on that I wasn't being honest with them (because I was also very adept at lying and half truths and manipulating to get what i wanted...hehe stilll am but to a lesser degree i hope!)...i was basically trying to be this mask or disguise, 24-7, and i had to watch myself constantly to make sure i didn't say anything to blow my "cover"...for people to see the REAL motivations i had behind hanging around them, etc. I'm not saying that's your case...basically what i mean is, for example, there was a guy i was obsessed with (and in reality, he wasn't even someone I truly CARED for...it was this fantasy I created, and he was only the human subject...on a tangent here, but i find it fascinating that I had such a rich fantasy life that for five years I obsessed over this guy because i thought he was the same thing as the guy in my mind. when i first went emotionally numb, he was the first person i lost "feelings" for...yet I really never had them for him!), and i would make friends iwth his girlfriend and fear the whole time i would blow my cover..that she would find out why we were REALLY friends...so i became more and more fake and manipulative...etc.
and my fear of being delusional was a fear of losing control and blowing my cover, or doing something that I wasn't monitoring, and in doing such my real motives would be "discovered"...
basically I wasn't being honest with myself.
maybe you're afraid of things you're hiding from yourself? could be possible...i mean, if you are afraid that you have this psycho delusional side, maybe it could simply be that there are parts of you that you aren't really familiar with...parts of you that aren't really THAT threatening, but because they're unknown and because you may be terrified of the unknown you think "oh, if I don't watch out i could turn into something terrible!"
i don't know if any of the above applies to you, just kind of hyper and a.d.d. and rambling right now...maybe avoiding my OWN feelings, i bet i am
