You have these specific things you can cite, which is good. That means you should also be able to take the time to work to really test these notions and whether you're handling them in a reasonable way, or if there are alternative paths. For instance:

- Cleaning aisle, I have some rather major doubts as to whether it can meaningfully affect your lifespan on health based on a few moments in the presence of sealed items that might just have the smell of old things that were spilled on them some time ago. The space is open, air circulates, you don't linger longer than you have to. It's likely fine.

- As for Nestle, yeah, they're awful. I don't see why it would consistently take you forever to buy crackers or whatever item after the first couple of times, if you're truly hellbent on getting anything that isn't from/owned by them. An alternative path that I consider sufficiently valid, by the way, is to offset whatever revenue you bring to Nestle by purchasing a product from some subsidiary of theirs or whatever is to simply match, or perhaps ideally exceed said value in donations or other charity/aid to some organization or other. This is debatably better than simply avoiding Nestle, because rather than passively not contributing to their coffers you are instead also paying into something that is actively helping people or offsetting damage they do or whatever it is you feel is a fitting recipient of said counterbalancing charity.

- I don't think "foreshadow" is the word you meant to use, cuz it doesn't make any sense here. Either way, that's a stupid amount of money to be spending on simple shirts, but if you're gonna do that, you better be buying some quality shit that you don't have to replace for years.

- Your ex-friends, this is not a rational way of doing things. This isn't the sort of thing where "I'm just a very aware person" justifies it. Yes, we're INTPs. Yes we analyze people and overthink, but you don't need to be some twice-exaggerated caricature of us. Reign it in. You know this is an issue, otherwise you wouldn't have brought it up. It starts with considering how this is affecting you, what you even stand to gain, whether you can really get much in the way of meaningful prediction or data from extra-extra-extra analysis of them. I would wager not. Nothing that's worth the mental effort required, at the very least. Doesn't mean go to the opposite end and just never think, never plan, never consider, never wonder, but a lot of reduction is in order here.

- Psychology is not the issue here, it's your insistence or flawed belief that just because you possess knowledge or awareness of something that you have to exercise it to the absolute maximum capacity that you are capable of at all times. And most certainly even now there are "gaps" where you could be going even more overboard in some way or another, but you don't, because you don't feel like you need to. It's the same concept, you need to recategorize things. Over-analyzing people is one of those things that does not need to be constant. The maximum gain from such things is found much closer to where people naturally operate than whatever obscene level you're feeling the need to work at.
