Lost

ok..here goes...this is a somewhat long, convoluted tale, but if anyone out there is fond or adept at problem solving, please read through..if not, skip to the bottom and see my absurdly long list of question.

A little over a year ago, I woke up in the morning with a strange, pressure like sensation in my forehead (please be aware of the fact that I was a recreational drug user for about a year and this change occurred about a week after a binge period of cocaine and ecstasy) -- accompanying this feeling was one of slight mental stupor. At first I associated the problem with a developing cold/sinus infection. However, as weeks passed, the pressure augmented -- I felt like my entire head was in a vacuum -- also the mental stupor evolved into something much larger -- I could not focus on anything, understand anything or articulate myself properly (literally)-- I felt trapped in the twighlight zone -- nothing made sense to me anymore and I thought I was going insane.

I saw specialist after specialist (general practicitioners, neurologists, allergists etc) and they performed numerous tests (like cat scan of sinuses and head, eeg and mri). They found nothing -- Meanwhile as I moved slowyly through life wondering what the hell was wrong with me, my depersonalization developed along with severe panic attacks.

I took every type of medication available (neurontin, depakote, nortriptyline, midrin) --they all worked slightly but the effects were fleeting, lasting only about 2 days. Then, I would revert back to my normal, depressed, anxious, perplexed, chronic pain ridden and intellectually hindered self.

Finally, I was referred to psychiatry -- my psychiatrist put me on clonopin and paxil because he thought that i was just really stressed -- again the cocktail worked at the beginning for about 2 days but then i felt crappy again.

Now, i am on 40mgs daily of paxil..granted, i feel slightly better but i still feel miserable.

What I really need to know is what the heck happened to me?

Could this have been a minor stroke?

Could it be severe anxiety?

What can be done for the head pain?

Why is it that now I can utter a few words verbally but not be able to continue talking coherently? ie, I say something to someone but then i forget what i want to say next and become lost and confused.

please please please,

any suggestions or just anything at all would be helpful.

thank you all in advance so much for your input
