Has anyone been in a situation where someone triggered your OCD to mess with you? What did you do?

my roommates are great people and very supportive, but they don’t understand ocd. they try to fix me by telling me things i’ve heard a million times before, and by doing things that actively trigger me as a kind of exposure therapy. i’m very particular about contaminants in my water, but i have a specific aversion to tap water, which is why i have my own water dispenser. every few weeks, i fill jugs with filtered water and keep them upstairs so others can use them too. after getting home from work, i filled my cup with ice water and, for once, didn’t inspect it like i normally would. i drank it down. when i went for a refill, the ice had melted a bit and i noticed particulates floating in the water, instantly recognizable as calcium and other minerals from our tap. i don’t explode when i’m triggered. instead, i shut down. the anxiety starts to crawl in. i felt myself spiraling while i pulled out the jug. i know it sounds stupid, but i swear there’s a real difference in smell between filtered and tap water. i checked it, sniffed it, and confirmed what i already felt. and once that thought was in my head, it took hold. i felt disgusting. i wanted to make myself puke. i couldn’t tell if it was anxiety or the water itself, but it felt like something was burning a hole in my stomach. i sent a message in our group chat asking about it, and one of my roommates said they had done it to prove i wouldn’t be able to tell the difference. they said water is water, so i shouldn’t care. i know they meant well. but when people who don’t fully understand ocd try to force those kinds of steps on you, it sticks. it reminds me of my parents. they do things like this a lot, pushing back against my compulsions, trying to help by challenging them. and sometimes, i do appreciate that. but this felt like too much. it crossed a line. and i just needed to rant.

This peaked during the pandemic, but for a while my OCD would tell me that everyone was actively trying to kill and humiliate me at all times. I was convinced that there were cameras in my house and toilets and showers, and i refused to shower for a week at one point. I convinced myself that people could see through my eyes and just felt super watched and paranoid at all times, and would sometimes have panic attacks at school because of these thoughts. I also couldn't leave my food alone in a room because i thought "they" would poison it. Who was "they"? Idk i just felt super paranoid all the time. These thoughts greatly impacted my life. For example, one time i was making myself food and i spent 30 mins picking out the right bowl because i had convinced myself that all of them were poisoned but one of them. However, i was aware that these were irrational thoughts, but you know how OCD is. I became heavily suicidal because since i thought people were planning to kill me, i wanted to be the one to take myself out. it was a super dark time and my mom wasn't supportive at all. when i opened up to her, she took it as a stab at her parenting and grounded me. i eventually saw a therapist and am mostly better but i still have my compulsions from this time. to counter these thoughts i created incantations i would recite in my head, and in my head it felt like these phrases were like magic spells that could, for example, turn off the cameras in my house. i had a different phrase for every OCD thought and some have merged into one, but i still recite them to this day and it takes alot of time out of my day. for example, before i shower i have to recite my phrases or else i feel super panicky. i also have rules for them? like i can't recite the same phrase more than one time in an hour or it will cancel itself out and i won't be able to "turn it back on" until the next hour. anyway, i know this was a lot of words, but im just curious on if anyone had a similar experience and what classification these OCD thoughts even fall into.
