Help!

hi! i'm new here! If i don't use the abbreviations correctly please let me know!
a couple of days ago my boyfriend got ill and v, i've been terrified ever since then that i'll get ill and v, constantly sanitizing my hands & washing them. how do y'all cope with this? i have no idea what to do because i just started thinking about how long it takes a virus to travel(i saw something that said 12-48 hrs) and it's been way past that. i started thinking about it and im not feeling great so i guess im just looking for people that feel the same i do, then i found this group. so.. how do y'all cope with this? what helps you guys?
