ahhhh! i thought i might have been the ONLY one in the world like this! haha... i don't know, i've pretty much gotten over it, but i was that way for a while when i lived with my boyfriend, and i liked to shower when i was home alone too... the hot water would make me feel weak and i would start freaking out like i might faint or something and i would get panic attacks in the shower... craziness! i found that turning the water to cool or cold really helped me feel better, and i also started bringing my phone (ipod/mp3 player/whatever ya got) in the bathroom and playing a play list of songs that would make me smile and keep my attention elsewhere... that's pretty much all i did to help me quit freaking out in the shower, now i don't usually feel the panic coming on, but if i do i try to do those two things and it helps

hope ya start feelin' better!
