Plenty of others have already chimed in why it's likely you haven't experienced actual burnout if that's the case, but an analogy might make it clearer:

You've experienced headaches, but never experienced a migraine.

When you get a headache you can just pop an over-the-counter pill to numb it out. Migraines are a fundamental neurological shift orders of magnitude more debilitating - that Advil would be like a drop in the bucket.

It sounds like you have a healthy relationship to work - keep doing whatever you are doing that is keeping you fundamentally mentally healthy!!
