Similar situation as you a few years back. Lured by the potential earning but not making as much as fast as expected and beyond my character to keep acting more successful than I really was in front of friends and family.
Left and went back engineering, fortunately without pay cut, doing something I prefer and most importantly no emotional burden
Since you are already asking this question, it is more of a matter of when and what...
Actually 60k is quite decent, how many years since grad?
