Made a goober mistake, I wanna hear about some of yalls.

I may or may not have forgotten to screw on the panel of a air handler, I put the panel itself on, but perhaps I forgot to screw it, i was made aware of it by my service manager, I didn't get assblasted thankfully, just told to double check (its my 2nd week in commercial).My anxiety has made me beat myself up over it I need to get over it.
