Sensitivity worse some days but not every day

My hyper sensitivity some days isn't too bad and other days it's just the worst, even though physically and mentally nothing is different. I don't work, I hardly go out; days are ultimately the same for me. Bit boring but the same old routine, which suits me as I really do not like my routine changing. Yesterday I wasn't very hyper sensitive whereas today everything is making me feel hyper sensitive. First thing I brushed my hair and it hurt bad. I washed my hands, had to dry them immediately and then the hand towel triggered my sensitivity. It's been a nightmare of a day from this side of things.

I've always been hyper sensitive to sound and touch. When I was little I couldn't bear to be rained on, if it rained I would cry and scream, my poor mum said she would take off her own coat and put it over me so the rain didn't touch me. Same with walking on sand on holiday, I hated the feel of it on my skin. This is sort of what led to my parents asking questions that would later lead to me being diagnosed.

Back to the now though. I find it odd how each day this sort of thing is different, it's the same with my keeping everything organised and tidy. Some days I have to look through everything just to make sure it's all as it should be and other days it doesn't feel important and I don't obsess over it. I find this side of autism bewildering, it doesn't really make sense to me.
