I was promoted about a year ago and have been struggling with the workload, especially as I'm short-staffed. I have been burned out and was sometimes so overwhelmed that I completely shut down and couldn't progress on any tasks. It hadn't been noted as I always managed to deliver.
However some of my inaction is coming back to bite me in the bum in ways I can't immediately fix. I am working my way through it, but I am so stressed and upset at myself. I completely recognise I should have asked for help, I just felt so inadequate and wanted to see if I could just pull through.
Should I email/talk to my line manager to explain what the past few months have been like for me, that things have slipped and that I'm working towards fixing it? We are recruiting more support for me and my team. For context I am middle-management in the public sector, and have been feeling a need to 'keep swimming' as I am young to be the grade that I am and wanted to prove I deserved the promotion. I am realising I probably didn't :(
