Yes!! I usually end up having bad anxiety and once I clear up my head I organize all my work and prioritize by deadline. There's times in which I'll be outtin extra work hours just to complete them. However, I rather do it than asking for help or saying no in fears that I will hurt someone's feelings.
I would look at what I know I can get done today, and the tasks I know I can't complete, put on a list to do tomorrow, or the next possible day. I wouldn't beat myself up about it, sometimes these things happen! But by planning ahead I have still kept myself organised and motivated to complete the tasks as soon as I can.
