I'm bipolar II with anxiety, ocd, and ptsd. I've started having these attacks and I don't know what they are. I'll be relaxing watching tv and I'll start to feel unsettled like restless inside. Then it's like a seizure.. immense pain-emotional and physical, I feel my muscles tense up till I'm in a ball and they contract and I can't yell only whisper for help. I feel so over whelmed and devastated like a parent just died, a strong feeling of doom and pain, lots of pain. I'm overcome for a few minutes and then it passes. Doesn't happen often but very distressing to say the least. I'd love to have a name for it. Anyone? No sweating like a panic attack and I'm aware so I don't think it's a seizure.
