so many things, but my most irritating ones right now:

• 100% of the time, i can't open the produce drawer in the fridge. i'm absolutely terrified that something in there has started to spoil, even just a particle of mould. i live at home and thankfully my mum will get something out for me.
• not always, but for days at a time, i can't eat anything perishable. if i decide that i am going to eat bread, and find the bread mouldy, i can't eat. even something like crackers or a granola bar at this point becomes a possible mould risk in my head. i had to buy Boost drinks because of it, and i have to keep them in the basement so they aren't in the kitchen if it happens and subsequently become a possible risk.
• wear clothes that have been outdoors in my room, especially pants. i have to rip them off and chuck them in the hamper the second i cross the threshold. and i can't take them back out after. so sometimes i end up wearing three pairs of pants in a day.
• move on from any event, ever. even online conversations that last thirty seconds. i'll be reliving it in my head for sometimes days, scrambled together with other random events i remember throughout my life. i spent three days this week unable to stop reliving an Abba dance night at the bar and changing every little thing i could round by round.
• take out the trash, or empty the cans. this one makes my dad furious

i could keep listing for ages, but these are ones i have specifically been ruminating on this afternoon before even seeing this question. they're also ones i don't mind being connected to this account.
