Fraser Crane might have said your guilt is causing you to manifest feelings of paranoia, as well as an overdeveloped tendency towards fastidiousness overblown to the point of borderline germaphobia.
No. I personally have not suffered giving a squat what people think of my purchases, nor do I let a few harmless (though, admittedly disgusting at times) mystery soils cause me to lose sleep.
If I did, I would take a moment to enjoy any new cannabis laws my state may have passed, shake it off, get back on that horse and continue to buy whatever I wanted.
Unless, of course, the guilt catalyst has a point. If you have vacuums lining your halls, in your shower, under the bed, etc,... you may want to pull back and ask a professional to help you figure out what void it is you’re trying to fill with vacuum cleaners.
And try not to worry about bringing in fleas. They’re all over every lawn ever, and they don’t survive indoors without a cat or dog. Of course now our pets take pills for that, Riiight?
