Please tell me I'm not alone.. it's a bit embarrassing to talk about this but does anyone have this issue ?

I have some sort of paranoia of fungus and absestos etc.. it stared after I gave birth , for example I have toe fungus and due to not being able to take medicine for it bc of breastfeeding I have fears to where I'm gonna get it on my scalp and my hair will fall out and due to that I get anxious to touch anything my toes touch for.. for example I won't sit at the end of the bed bc my toes are there.. or my cat lays in the shower all the time so I won't pick him up bc I imagine he will have fungus on his furr bc I shower there and my fungus stays on the shower.. or I won't sit on the floor if I do I get super stressed out about possibly getting fungus on my body .. anyone else what is this! Does it go away?

And if by any chance I touch something I think my toes touched I have to either wash it.. throw it away or shower depending on what it was! It's so horrible.i hate it!
