TIFU by not knowing how bleach works

So, I'm not crazy ignorant, or stupid, or niave. I swear. I (36f) know you never mix bleach with anything like vinegar or anything with ammonia (or with anything else ever). I know you don't touch it, it's highly corrosive if left in certain types of bottles.... but I've never actually used it before.

I usually use vinegar or spray 9 (for the really icky stuff) or sometimes the Mr. Bubbles, (which btw, works way better on calcium spots and lime scale than CLR). And I always try to avoid the really harsh chemicals. Both for safety and to not pollute as much as possible.

Unfortunately, I got really sick, which turned into a massive infection, which turned into necrotizing faciitis, which led to me having to have a large bit of flesh, muscle and fat removed from my hip. I was down for about 8 months. Then right on the tail end of that, I caught mono somehow (I'm single and typically don't have contact with people and am a big handwasher). Needless to say, I was down and out for a hot second.

Anyway, my brother and I bought my dad's house off him when he retired and he pays a really cheap rent to live with us and help out with the bills. They're boys, and my brother does all the typically boy chores around the house. Fixes stuff, garbage, lawn, shoveling, he does the majority of the cooking, and we share the pool. I do the typical girls stuff. Dishes, floors, dusting, (they both do their own laundry) tidying, groceries, bills and my brother and I both work full time. Dad is retired and doesn't do housework. We're both happy with our arrangement.

When I was sick my brother and dad both stepped up and took over everything except the bills. (Both of them have memories like a sieve when it comes to things like that) and they did a great job on their own mostly. But because they're not used to doing certain things, they missed a couple things here and there.

Because of the location of the wound, I couldn't shower and was forced to use the bathtub to sit on the side and use cloths and such to just clean myself like that to avoid getting water in the wound. So I missed that they were forgetting to clean the shower. So now we have mould. Just a little in the shower, but the damed stuff is so tough that even ripping out the caulking and re-caulking didn't eradicate it.

I tried vinegar, spray 9, scrubbing, recauling, everything is could think of. No dice. So I finally broke down and said screw it, I'm going to have to go nuclear on this shit. I broke down and bought my first bottle of bleach ever.

Now, I'd already heard horror stories of chlorine gas, minor explosions, all sorts of trouble with pipes etc, so I rinsed the shower down hard with water for a good hour before doing anything with the bleach.

Here's where I fucked up. I didn't realize you're supposed to dilute bleach. I knew you COULD. But I thought to myself, like a niave little dumb-dumb I need the psychotic hard shit for this job. I mean, its not like I've had a computer in my pocket with all the worlds information at my fingertips for 20 years right? It's not like I don't research HAIR TIES to make sure I'm getting quality for a good price for 5 hours before I commit to effing hair ties. It's not like I got an English degree (which is basically a researching degree) 12 years ago and know how to research how to do new shit before I do it right? Like God damn. Im such a Dumbass.

So I poured the full, 100% strength, deadly chemical into a (thourouly researched so it didn't eat through the material) bottle, and added exactly 0 water. Then I went on my merry, shit brained way over to my shower and began spritzing that shit around like I was trying to water the Sahara desert.

At first, it was fine. I had the fan on, a window open, the bathroom door open. I was all good! Then, I started blinking. Like... blinking. Then, I started coughing like a 60 year old smoker who started smoking at 13 and smokes 2 packs a day. Then my nose started to burn like I'd just snorted lemon juice, vinegar and salt all at once, I sneezed, smacked my head on the shower door, turned to calm my whole face (which was in full revolt at my stupidity), and ran the sink tap and started snorting water and washing my eyes like that idiot in science class, Scott, who thinks the way you mix chemicals is with your face directly in the explosion radius.

So now, I'm choking on water, spitting up phlegm and a bit of bile, and I can't see through the tears of my brain dead actions.

I stumble out of the bathroom, close the door behind me with the fan on, the window open and praying that that's enough to clear it out.

Then I finally find my last brain cell, and it asks me if I was supposed to dilute the stuff. I finally pull that little computer thingy out of my pocket and somehow muster the brainpower to operate Google. That's when I learned... I should have diluted the bleach 10-1 with water.

It's been 4 hours. 3 XL cups of tea, a large glass of lemonaid, 3 hours of fresh air, and a whole head shower in my kitchen sink later and I still smell bleach. Im not in pain, having trouble breathing, or feeling sick, so I assume I did minimal damage to myself. Actually, everything is back to normal except my sense of smell. I feel like I got lucky that the death of my entire brain hasn't actually killed me in this moment.

TLDR; Moron who has never used bleach in her life refuses to do any research on how to use bleach, and now, only smells bleach.

EDIT: For anybody who might be wondering, according to my brother, the bathroom still smells a little like bleach, after about 5 hours now, the mould has been obliterated as far as I can tell, and I did in fact, finally get to rinse out the shower.
