It is a rare thing indeed to have a job doing something you love and continue to love doing it. Once it becomes a job, all the unfun stuff involved can no longer be ignored or pushed aside, as it can be with a hobby.
Everyone is a wage slave in some way, gotta eat, sleep somewhere, all that. If you are good at something, your slavery is less of a burden. Being the boss is, IMO, worse. All the BS becomes your problem.
Find something you can do without going crazy, and use your spare time (if any) to unwind. The stereotype of the “starving artist” has a long lineage.
