@Double edge and lilo: Thank you so very much. I deeply appreciate the feedback.

For some reason I just knew schizophrenia was going to come up, as I checked the negative symptoms and I pretty much have them all. Of course this is not enough for a diagnosis but maybe I should relay what makes me think that it's a high possibility.

Yesterday evening I experienced the most bizarre hyper-mania ever,and it was freaky. So, I had this horrible headache,weakness and fatigue but for I couldn't stay still so I had to circle listlessly around our tea table for nearly half an hour,before I sat down on the floor laughing and crying at the same time. I couldn't stop myself and I started talking to myself in a very satirical manner. It's really sad. Applying this to your question about distinguishing reality, well to me,that is reality. I really can't distinguish anymore and I feel like I have lost a key cognitive function in my brain, I lack insight or perception, that thing that makes you actually think about your actions is nearly gone now. And I have this chronic apathy, maybe apathy is not the right word but more like an inherent inability or disability in genuinely feeling emotions, I can express them fine but I don't feel them. I also display inappropriate emotions many times, like when something is really serious I chuckle or even burst out laughing which makes people angry. And when I am yelled at I grin and I smile for no reason. They aren't genuine because I don't feel anything related to joy or happiness, it just happens. It's really embarrassing, because sometimes I find myself laughing in public...

Continuing what happened later that night, well...I couldn't sleep and literally went 'crazy', I acted like a sugar-induced hyperactive five-year-old. I couldn't stop talking and joking and jumping, and doing all sorts of unreasonable things and then I had a very bad mood and went to bed upset. Maybe this should be added to give a better picture, there are days when my brain feels like it's on fire, it's not a headache per say but more like this burning feeling like it's being fried. And I have horrible screaming fits, but not because of the pain, I don't feel pain,I just feel like screaming and I scream until my veins get enlarged and hit myself hard, actually choking and strangling are the only ways that seem to calm me down. But because this is extremely dangerous,what I do is tie a thin rope on my arms or legs until the pulses are gone. Sometimes using tape makes it better.
There was a slight chance that all this might be DID so I posted on another web,if you have the time please check it out and see if it's relevant:
Can dissociative identity disorder be caused without trauma-psychforums.

Sorry for troubling you with all of this, this is honestly my only resort, I am very grateful for your opinions and insight. Thanks a million .
