hi. my "Bipolar I" started with a switch from psychotic depression to a psychotic mixed state, which ended in a lovely hospital stay, complete with involuntary shock treatments.

so...if its getting intense, id recommend you call someone who can prescribe something. if its not too, too bad, id say exercise, try to get your sleep in order, try to get some social interaction (if possible...), and...

get outside of your head, too. that helps me, tremendously. a class, the news, writing, art, volunteer work...anything...to get outside -me- and into something, anything bigger, more pressing.

hope this helps. sorry you're going thru this. :-)
