I work at a dunkin donuts thats still open and doesn't seem to be going to close anytime soon.

I want to leave because I'm borderline asthmatic and was told by my doctor "I would find a way to stay home and not go out if possible"

If I leave I screw over my boss and she will essentially have to do my job which isn't that hard but for some reason the threat of death isn't enough to make me overlook putting someone out.

Can someone please let me know what I should do? I have incredible social anxiety and the thought of what I need to do is incredibly overwhelming. I'm also not sure if I quit I'll be able to collect unemployment to pay bills and stuff or if I should gamble and wait until it gets terrible where I am and we FINALLY close.

Anything criticism or something is helpful thank you.
