Terrified I have fp

(I refer to throwing up as "being sick" for my own comfort. Just clarifying so you know what I mean)

I need to rant and get this out of my system because im hoping it'll help. Especially if someone else is going through something similar. Around 7 pm last night, I had chicken tenders from a local grocery store for dinner. I didn't notice anything off about them, and neither did my family (who as of right now seem like they feel fine). i even had more of the chicken for lunch today.

Last night, I started to have some stomach pain. Idk when it started exactly, but within a couple of hours of eating the chicken. I didn't feel too nauseous, and I went to sleep fine. The pain is like a constant dull cramping that feels similar to hunger, but obviously isn't because I feel it even after I eat, and it feels kinda full. It's 3 pm the next day, and it hasn't gotten any better or significantly worse. It's definitely worsening, but not by a lot. I have no appetite, and even drinking water feels a bit weird. I haven't been sick in around 12 years, and I dont know what it feels like. I've also obviously never been sick from food poisoning, and I have no idea if I should suspect it. Im just so scared.

I also do experience nausea as a symptom of my anxiety disorder, which i have started taking medication for, but it doesn't feel like this. It's usually more of a throat feeling than a cramping one. My anxiety probably isn't making it better, though, and i have a concert tomorrow, so im really hoping I'll be okay for it. Uhghhh.

If anyone else is feeling scared right now, feel free to comment or message me. We're in this together, and sometimes it helps to talk to someone. I know for me, at least it does.
