Just following up on many of the comments that ask, are you allowing enough rest/recovery? … I have a Garmin watch that gives a training status that I find a good indicator of whether my exercise is benefiting me or not. If my “load” is the same or going up and my “fitness” is going down it’s a good indicator that I’m not getting enough rest or that my current exercise has plateaued. I find it a good prompt to rethink what I’m doing.

And while I’m not disagreeing with this, it is also ok to check in with yourself and notice “ok, I have uncomfortable feelings” but then ask the question “Am I in danger?”. We all get uncomfortable some times but we’d never do anything new if we always stop ourselves just because we’re uncomfortable. The trick is learning the difference between good/safe uncomfortable and bad/dangerous uncomfortable, and to learn that you need to practice being with your feelings. Read up about exposure therapy.
