At my old job (which I hated) I was washing semi trucks. I normally do not experience sensory overload, as my sensory issues are relatively mild, but every day working there by the end of the day I would feel absolutely horrible, and I'd have to take at least 20 or 30 minutes before leaving because my mind would be shut down.
During my last two weeks working there, I discovered a little trick I guess that would help me get through the end of the day without wanting to kill somebody. I would still feel mentally exhausted, but not quite as bad. We used these pressure washers, and I found that I could calm down a bit if I focused on watching the tip of the spray gun, just following it back and forth as I sprayed, following it with my eyes and sometimes moving my head too. I still felt really out of it, like I was in a trance or something, but if I hadn't have done that I probably would have had a meltdown one day and just totally quit.
It seems like an extremely odd thing that it actually calmed me down, of all the things I could have tried. I don't even know what made me start doing that.
