Andy, you are going through what many of us have experienced in our lives and sometimes a break is necessary. As others have said, this is not supposed to be a stressful hobby so if it is for you, walking away for awhile is a smart thing to do!
Check in like you said and someday, maybe sooner than you think, the urge to be creative will come back to you.
I was expecting to see another Gearz winning build from you soon, maybe next year!
Take care.
