Is Anybody Else Bipolar??

I was diagnosed as being Bipolar when I was 18 (I'm 24 now) and I tried every drug imaginable until I was put on Lithium Carbonate 2 1/2 years ago. Its the only thing that keeps me level most of the time. I was just wondering though, do the changes in the atmospheric pressure affect me more than most people because I am bipolar? I've noticed that like a few hours before it starts to rain I get SUPER depressed. my friends and family notice too, they're like "its gonna rain today isnt it" everytime i get the least bit b*tchy. its awful. i was just wondering if anybody else experienced this. it's been raining here since yesterday and i am about in tears. :(
