I lose things all the time and your post really resonated with me. I hate myself when i lose things but lately what I’ve been doing is applauding myself when I can find things or put things back in their place. It’s been really rewarding. I’ve been known to lose my debit card once every three months (poor Wells Fargo) but I’ve fought my brain who says “you can put your card back later.” I know this doesn’t help you find your things right now, but please reward yourself when you find them or put them back in the same spot. All I have to do is congratulate myself mentally like “YES YOU FOUGHT YOUR BRAIN AND DID A GOOD THING.” Please consider starting doing this. I have faith in you and all of our adhd brothers and sisters here.
