I loved your question and was disappointed that there is no help because I also suffer from sensitivities to everything. It is very difficult some days. I find that I need to have cotton stuffed in my ears a lot. The daily sound of dishes hitting against each other can be too much for me. The part that is really hard is when I need to tell my children that I need them to lower their voices or just not to touch me because I can not handle it. The girls did not sign up for this (neither did I; who signed me up ) and I feel bad that they are affected by it. I have even told my poor husband that he smelled and needed to shower (not a good thing to say to a man). Perfumes and deoderants need to be scent free.
So my answer has been to, plug the ears to soften the noise. I am very careful with perfumes and use scent free soaps and lotions. Touch - well I hide in my bedroom when it gets really bad. Light - I wear these polar sunglasses that wrap around to block out light ( my girls say I look like a dork but I don't care, it's be a dork or a crab, they choose dork). I only wear them outdoors and when I am driving. I also have the lights in my office dimmed or taken out; at home the shades are usually shut. Somedays I live like a hermit.
I hope you find some relief and know that I will be praying for a solution for us!
Have you tried running a fan at night to help block out unwanted noise and keep you cool? I have always done this to help block the ringing in my ears due to tinnitus. As far a deodorant goes, I finally found one that works for me, and I think I've tried every one on the shelf. I buy Dove sensitive unscented. It truly does not have a scent and works great.
