hey i am going thru the same thing, as in, in the head. Its has come to a point where i surprise myself on my behaviour, and paniced myself into believing i was schidzo , i tried the doc thing but din work out coz i dont want to take any meds, i keeping a very, very close watch on myself, noting patterns and triggers and food cycles, coz at the end of the day, i beleive 90 % of the people are bi polar, they have to be, just notice people around you, very few on whom you can depend on to have a constant mood pattern, some of them are high on religion, some on meds, some on drugs and some on work,
i am giving myself sometime, to self analyse and hoping my instincts kick in to help me out, coz i dont think anyone else can, the doc would have to be 'you' inorder to help you, coz, dont you think its obvious when you are narrating you cycles, they are subjective to your current mood swing,
when i am in manic i feel no work spoken can be harmful unless i make it, and when i am depressed even a smirk can make me feel worthless and lonely,

guess too much on my head, well this is my take on it, hope it helped in anyway, and if you wanna talk more please let me know, feeling like a bouncing puppy right now....

cheers !!
