Stress rash?

About 5 days ago I woke up at 3 am with a massive need to itch my skin. I scratched for hours and couldn’t fall back asleep because I had an awful headache. The night before my partner got laid off and I am currently in the midst of working 14 days straight. I’ve had massive hives in clusters on my face and joints. My feet and hands are itchy as hell but I don’t get hives on them. Benadryl helps a bit. The larger hives on my face have started to reduce in size but they move and new ones form. My diet hasn’t changed, I checked for bedbugs for hours. My scalp is so itchy I want to cry. I laid in some catnip and thought it may have been that, but I cleaned everything I touch since and I’m STILL itchy and ridden with hives all day, it’s almost been a week. I don’t have allergies, no new meds, I’m guessing this has to be stressed or burnout related. Anyone ever deal with this? I don’t wanna go to urgent care if I don’t need to, but my partner thinks I should. I don’t have any other symptoms.
