How do you deal with the crippling anxiety for WFH?

As asked in the title. During office timings, I am really anxious to the point that I am unable to relax during lunch breaks as I am afraid I will get a message or a call that I might have to jump into. I know it sounds stupid, but I spend nearly 10 hours everyday with crippling anxiety. It has become so bad, I am considering quitting to work on myself just to get rid of this anxiety. However the Current market scenario doesn't allow me to me do this. I have asked my friends and family about this, but everyone says 'don't quit', 'work hard' Etc. I am sick of hearing this.
