How to relax?

Its christmas eve my employee just left me high and dry and ghosted me for the day with no notice, so I had to do everything myself.

I had a panic attack today and now that I want to destress I dont know how to. Everything I do I feel like I should be doing something productive. Im usually work 24/7 kinda guy (I know that's not good business) but today was too much, and I want to relax a bit but I frankly dont know how LOL
