Every so often I wake up in the middle of the night, seemingly 4 hours after I go to bed, I use the rest room, and lay back down. The first thing I notice is that I start thinking really weird almost deranged thoughts that are blanketed in fear. Then my hands and my feet get very hot then this fades into complete nothingness NOT TINGLING My body is not asleep feeling, it feels like my body is just gone. Then I notice the only thing I feel is extremely shallow breathing in my lungs, and I feel my neck and feel a barley there pulse. Then I start just knowing that I am going to die. But I cant think straight enough to call for help. So I just lay there and wait to slowly fade away. Then about 10 minutes or so later I slowly start to feel my hands and feet again, then the rest comes back and I am freezing cold. I start to warm up in a few seconds, and then my mind seems to return to normal and only then can I fall back to sleep feeling completely exhausted. It is hard to describe exactly how it feels, but it is terrifying and very problematic. I am always afraid to go to sleep because I don't want to wake to this anymore. PS It is not sleep paralasis because I can move if I even think that deeply. While I know that no one here should diagnos me, I am more worried about seeing if any other people experienced these symptoms, and if they are because of my Bi-Polar , deppression, or paranoia? I have just aquired a blood pressure cuff to check my blood pressure when this type of thing happens. I figure the more I rule out the better I will feel. Thank you to anyone who can help!
