Hi, this might seem a bit silly, but I have OCD, so bear with me! There's been a plastic storage tub collecting rainwater (unintentionally) in our garden for the last 3 to 4 months - it got left out by mistake, and because the lid has holes in it, it gradually started collecting rainwater. I could see it had gone green so decided to carefully empty it away today while I was out there doing some other gardening. I planned to tip it upside down and let the water slowly drain out of the holes in the lid, but as I tipped it, the lid came off and the water came flooding out. The smell was as disgusting as you'd imagine, and I jumped back away from it. I had to go back to where it was briefly to turn off a hose that was running, but held my breath because of the smell, then went inside. Then I started googling, which I know I shouldn't do, and kept reading about the risks of contracting legionnaire's by breathing in aersols from stagnant water, and how it can be fatal, and now I'm in an utter panic that I've breathed in all the worst possible bacteria and will end up really sick in the next few days. I washed my hands plenty (which I always do anyway, but of course went way above my usual) and changed my clothes, but I can't shake the feeling that it was a breeding ground for dangerous bacteria and I've put myself at risk. I don't even know what I'm asking for here, I think I just need to be talked down from the panic I've got myself into. I hate OCD/catastrophising, and I feel simultaneously stupid for panicking over nothing & stupid for almost inevitably contracting a fatal disease. Please tell me you've all emptied out buckets of stagnant water and been absolutely fine before I work myself into a frenzy!
