Ow, my head!

emeto warning! I know some people don't want to read about nausea and what comes with it, so this is a warning!

So, I have frequent headaches. Often enough that I usually decline meds for it in fear of becoming dependent/tolerant of it. However, not frequently enough to really tie it down to one thing. They usually happen after long, loud, social days, but other times it can happen after I change the cat's litter. Would this be a kind of sensory overload, or just connected to heightened senses? I also have frequent nausea, basically, all the time, after, before, and sometimes during eating. To the point where it's become a normal thing. I never actually vomit though, which kind of makes it worse. It feels like starting a task and not seeing it through, like when I yawn "wrong". I'm seeing my new GP soon (which is in itself something to worry over), and I'll tell them about it. Maybe they could also point me in the right direction to get various things, like an official diagnosis of gender dysphoria, depression, and maybe ASD. Who knows? All I know right now is that my head hurts.
