I overshared at work

A scenario came up at work yesterday, where I felt very pressured by my team to supply resources that I’ve been advocating for but keep getting turned down by senior administration, given the current COVID financial pressures.

I was so angry about the lack of control in that situation, and I feel like I over shared a bit with my team in terms of the support I’m not getting.  I wanted to be transparent, but also felt like it might have come across as complaining.  I find it difficult to keep the veneer of calm and cool when I both dislike and disagree with a lot of the senior decisions.

Can you help me move forward please?
