Omg I'm going through this right now. Haven't slept in two days and it feels like every muscle in my body is tensing up on me which makes it impossible to relax. That and I get sensitive to sounds. Today my bird was talking and screeching and I would cringe! Then from lack of sleep I think I hear stuff like a phone ring when everyone's here is on silent. I even woke my bf up and said "answer your phone!" He looked at me like I was nuts. Needless to say I am definitely calling pdoc first thing in the morning! At least to get in to see a nurse. Hope you get over this feeling. I was in tears today because I was just so exhausted.
