I'm going through something similar. I'm a new c-level executive, but I'm having difficulty adjusting to the responsibilities, and I'm not used to doing this type of work. I'm having problems with imposter syndrome. I'm disoriented without my spouse who passed away, and the loss of my lower-level job and co-workers I lost when I was laid off after many years. I also cycled into hypomania, and now I'm struggling with the low that follows, plus anxiety. Trying to be productive and consist is tough, and I know I appear to be extremely different to everyone from quarter to the next.

I'm struggling with whether I can really do this long term. I just started lithium yesterday. Perhaps this addition to quetiapine and gabapentin will make a difference.

In the meantime, I keep telling myself to put off drawing conclusions about my job performance.
