panic room

oh god. i feel so nervous/anxious right now. i don't even know why. please don't let this be the precursor to a panic attack. i haven't had one in years. my body is refusing to cooperate. what's going on? can i just dig a hole in the ground and either a) curl up and sleep, or b) shrivel up and die? i can't deal with this anymore. time is passing by too quickly, and i'm losing track of bits and pieces all over the place. it's confusing to say the least. and the constant oscillation between hope and despair doesn't help. it really doesn't. i'm running out of air.
