Dealing with COVID Anxiety

my mom got covid last week, and since then, it’s severely triggered my health anxiety. if there’s a chance any of my clothes or anything touched something that could’ve had covid on it, it’s like i HAVE to wash it or else i’ll get covid. it’s made it really hard to get dressed with clothes and sleep on sheets that my brain thinks are clean. i’m pretty sure this has gone beyond reason since i’ve washed some of the same clothes twice in the past two days when i didn’t even wear them, and i can’t use two of my normal bags since they could’ve had contaminated clothes in them. am i taking things too far? i’m really struggling to get through the day even with worrying that something on me is contaminated.
