Getting through bad days at work?

Sh

So I need advice for getting through bad days at work??? Y'all I work in an office and I really just had the WORST day. I'm currently crying in my car but that's not why we're here now is it..ive had bad days before but today felt like the end. I wasn't doing anything good enough, my anxiety was full speed and everyone had their own two cents to give me about how to do my job. I'm trying my hardest and I want to know how y'all deal with rude comments and such at work? I work in an office with all ladies...so it gets kinda catty. We were in a full staff meeting and someone brought up how I only did " x amount of work." And how she had to go back " and fix everything for me." And that entailed my boss not being happy with me..as for everything else my boss has been passive aggressive, I had a brain tumor and the one of many affects of it was short of memory...she talks about how I'm forget full and how I ask questions over and over, I'm not really looking to quit I just need to know how to deal with it.
