how are we staying positive even when family doesn’t seem too positive?

TLDR: was just diagnosed — fiancé told me today “you might just feel funny every day” how are we staying positive when it feels like it’s wearing our partners/family/friends down? I (26 F) haven’t known a day in over a decade where i haven’t taken tylenol or ibuprofen like it was candy — i wish i was kidding. It started when i was in high school, i can’t remember a day where my head didn’t hurt one way or another. even then my own mom didn’t believe me. Last week, i had my first hemiplegic episode and ended up in the er. Did all the work up, stroke test it all. I’m healthy as can be (which honestly shocked me. i’m fat as fuck and eat like shit but i digress), I just started my first preventative and i know that it’s a process — i’m not going to find relief off my first medication or relief within my first week of finally treating a decade long disorder that’s affected me daily. this morning my fiance asked how i was feeling, to which i replied honestly and said “my brain feels too big for my head, and im nauseous but that’s it” and she said “you might just feel funny every day” and it just was super discouraging. if you read this far — how are we staying positive even when it feels like our partners are struggling with how hard it is to stay positive?
