What's the cost? It only takes a few min to submit on Product Hunt.
I agree that you're better off befriending the PH editorial team (since they decide who gets featured and who doesn't).
But even a simple launch gets you a backlink and "some" traffic. So I wouldn't say "you're doing it wrong" for doing something with no downside and some upside.
If you feel burnt out, chances are you're not getting the results you want. So instead of concluding "burnout is affecting my brain" I think the better reaction is to ask yourself "what needs to change?"
