Help..

I'm not sure whats wrong with me...I think either a brian tumor or schizophrenia

here are the symtoms..If anyone has any clue what this is please say so

- voluntary and involuntary twitches/shaking in my legs/arms

- somtimes when I lay in bed at night...It feels as if my entire body is shaking...Very very very slightly, as if my bed was trembling or there was an everlasting small earthquake

- on and off..Half of my left hand goes numb/tingles

- visual hallucinations...This has only happened a couple times, but i'll see 3 'dots' or orbs floating 10-15 feet away...And then one of them will fly towards me and it flew right past my face...When I tried to 'grab' it with my hand it dissapeard.. This happened one night really late..1-2 am when I was really tired, but it happened like 30 times in a row because I was playing with them sort of...And I was outside with no lights on but the orbs seemed to glow...Blacklight like but really dim.

- weird dreams, i've had lucid dreams for several years now [lucid dreams = you know your dreaming], i've even gotten to the point of being able to pause or rewind some dreams

- random spurts of the chills...Even if im hot or wearing a sweater and pants or somthing, oh..And I live in southern california where its never cold.

- insomnia...Somtimes I go 3-4 days without sleeping at all..I'll lay in bed the entire night, not moving at all, thinking..Its like my mind keeps me awake

- I have trouble finding the right words during conversations, or someone might say somthing and i'll reply but my reply had nothing to do with what that person said...Although in my head it did?? Not sure if this makes much sence..

- I dont think the same way any of my friends do, or anyone I know for that matter...At all..Like litterally everything i'd think about somthing that we'd all see...Is nothing like what anyone else would think..Its really weird and frustrating, unless I try to think of what they would think about..Like if I put myself into their mind...Then im right on everytime...Again, very weird.

- trouble eating...Somtimes I go 20-30 hours without eating a single thing..And im still not hungry, or i'll eat say 1 peice of pizza..And then not eat until the next day just because I never got the urge to go eat somthing, im not anorexic or bulimic and I have no fear of becomming fat whatsoever, im 5'11 and weigh 170 pounds..Athletic..I exersize daily.

Thats all I can think of at the moment, although I know theres more...Uhm I think I should go see a doctor but i'd like someone else's opinion first, also my medical insurance runs out at the end of july '05....Say its a brain tumor, dosn't it take months to prep for a big surgury like that?? So is this all pointless anyways since I cant afford healthcare anymore?

Oh..And im 'very smart', I took a professional iq test and scored well above collage/university graduate..Although I only went to college for 1 semester.

I smoke marijuana on occasion as well, when I cant sleep or cant eat. And I have expiermented with hard drugs in the past although never got addicted and never did anything more than 1-2 days in a row and never twice in the same month. I'm very precise in everything I do...

Anyone have any ideas?
