I keep making mistakes at work

I’ve worked in a high performance marketing job since my son was 8weeks old. I recently left my last company where I was in a management position because it was too stressful.

Unfortunately the new job I started 5 months ago that was supposed to be chill is very much not, and my one year old doesn’t not sleep well.

I’m chronically sleep deprived and making a lot of STUPID mistakes at work in the last couple of weeks. I was doing pretty well before and received a great annual review just as it was all happening.

My boss is a very intelligent person and seems to be incredibly put out with these little mistakes. Frankly he’s starting to FIND things to be annoyed about that aren’t even my fault (like not knowing each of the nearly 100 staff members by name by now after a super busy few months).

I feel mortified as someone who normally has it all together. It’s literally been like six things in a row to where every interaction I have with him, there’s something I missed or got wrong etc.

Does anyone else have this experience, especially in a high expectation, management role?
