Lack of self confidence or something else?

I’ve been struggling at my job over the last year – procrastination, unengaged, etc. My thoughts have been that I’m bored, I hate my job. I’ve been doing the same thing for 11 years. I don’t care anymore. Mondays are especially difficult. I’ve had several discussions with coaches and thought it was an issue with self confidence. There has been a change in my upper management over the last couple of years and my work environment is very different now. Previously, my managers heaped praise on me and my work and were very supportive. This isn’t the case with the new management. I’ve been thinking my lack of engagement was due to low self esteem b/c I have sought external validation; however, now I’m wondering if the external validation was a source of dopamine? Any thoughts around this? Thanks
