This happens to me too. ☹️ When I'm feeling better, I try to thank my partner for being so understanding when I'm irritable from pain. He often will politely ask me now if I need help getting my meds, putting on pain cream, getting the ice or heating pad, etc. We've been together almost 8 years and he's gotten to know my needs pretty well. I used to have an info card for him "in case of this, I might need these things..." because my mood sometimes spiraled too and it was hard to verbalize my needs. You're definitely not alone! I hope your boyfriend is understanding and supportive!
