I've always been pretty confident in my job - if not the occasional feeling of impostor syndrome when I was promoted. But I've realised that for the past month or so I've been just less motivated, much less sure of myself, and probably less productive in general.
There's been some stuff going on in my personal life that's probably had an impact. But also just in general feeling less "with it" at work.
Fortunately I have a holiday next week - so will get some time away which I hope will help recharge me. But I'm wondering if I should say something to my manager - acknowledging that I've been feeling a bit burnt out, but will come back refreshed after a week away? No one has said anything to me that suggests they've noticed, but I'm paranoid they are forming opinions about me based on the past few weeks.
