Classic side effect of being depressed is that you stop caring about everything. Which can be a good thing in the long run, in the sense of realizing that you probably placed importance on really unimportant crap in the past, but in a more immediate sense it can mean you forget what's "socially acceptable" and tend to be brutally honest with everyone (including yourself) which people can find very confronting/uncomfortable or even funny/pitiable tbh depending on their mindset. Not saying that it's right, just saying it's reality unfortunately. A lot of people, especially in management, are spectacularly **** people
I will also say though that if you're down low, you tend to read everything with a very negative bias. Sometimes looking back on things, you realise that the emphasis/importance/interpretation you were placing on something could completely be missed by someone else, leading to you misinterpreting their reaction as callous/careless/etc. I dunno the specifics of your situation, just saying watch out for reacting from a depressed mindset.
