Oh, blue! I have major sensory issues, too. It can be so very over whelming.

I don't think anyone can understand it unless they have experienced it. I do think, however, that your therapist is supposed to listen to how it affects you and respond accordingly.

When I start losing sleep. I get worse with sensory issues. I have lost a lot of sleep this week and I thought I was going to die from the noises, the light, the voice of anyone talking to me, the fans, the AC (!!!), even tire noise with the car! I also hear all kinds of music mixed in with ongoing noises. I was ready to crawl out of my skin. It does become overwhelming to go to the stores, especially those with bright overhead lights, lots oof people and with other sources of stimulation. I guess I am trying to say: You are not alone and ... yes,it is horrible!!

I hope you can eat some bland food. If not, please keep yourself hydrated with liquids that give you more than just water. does, even though water is better than nothing.
Maybe get some ginger ale for your stomach to see if it helps? When my stomach gets really bad, I usually eat crackers and try to sip on ginger ale. Sometimes, for me, some of the pain is gas. I then do well with GasX (simethicone), which can be found easily in other products.

I hope you will feel better soon. I will check in again later. I am around. Feel free ot PM me anytime, as well.
