I'm a guitarist and get into this trap a lot. I'll get so busy I won't pick up my guitar for 4 months and feel guilty as hell. Then I'll force myself to do something I actually enjoy, start learning something new, then beat myself up when I get into it by thinking "I wasted so much time I could have used this knowledge years ago." It makes me depressed and I think I'm associating that with my music playing. That negative reinforcement creates a loop.

I need to start getting this "I'm doing it now instead of never" mindset going.
