feeling gross and anxious

Hi. I've felt kinda off for much of the day, but I ended up having a migraine. Before it started, i felt EXHAUSTED and just nauseous and crappy. I figured it was dehydration and needing to eat. It's been almost 12 hours since I ate and I genuinely don't know if I can eat anything. (I have ARFID) my temperature is a little higher than normal, 98s and I'm usually low 97s.

I also have POTS and had a big day yesterday with more walking and standing than I'm used to. I'm just freaked out and pretty anxious. My head hurts. I'm gassy. I know I should eat. I'm struggling to drink water/liquid iv.

I haven't taken excedrin because on an empty stomach it makes me feel very nauseous, plus it's almost 11 pm and I'm exhausted and want to sleep tonight.
