I should probably preface this by saying I have co-morbid bipolar disorder and C-PTSD, if that's relevant.

Last night I had a pretty severe meltdown while trying to sleep, similar to ones I've had in the past but even worse than usual. Whenever I have an "episode" or whatever, I start (thrashing?), my body tenses up and I squirm around a lot. I don't know what triggered the attack this time but I felt like I had lost complete control of my body. I kept saying "no, no, no, stop, I can't, I don't want to," and I was throwing out my hands into the air as if I was trying to defend myself against something. 

Luckily I became lucid enough to shake my boyfriend awake (he sleeps like the dead) and he physically restrained me and talked me through it until I stopped thrashing. Today I feel more stable, but it took me two hours to fall asleep afterwards and this morning I was sore in my arms and shoulders from tensing up so much. I'm not a very active person so admittedly I have very weak muscles, but it scares me to think I'm physically hurting myself when I melt down like this. 

DAE have similar experiences? Advice?
