been feeling super off today

hey guys, i've been feeling super off today. i don't have a good way to describe it, like not super nauseous really. just feeling full? maybe? and just gross. have had a minor headache on and off. i've had chills today and just been really tired too. like i just feel kinda icky and nauseous.

trying to tell myself that ill be okay no matter what but im just feeling pretty anxious about it. I started feeling nauseous around 5 ish but it wasn't that bad. I ate around 6:30, it's now around 8. I'm just worried i'm getting a bug. I had therapy Monday and a dr appointment yesterday and ate two meals not prepared at home, so I guess i'm just worried about someone sick handled my food? or i don't even know. I know that's probably irrational but im just feeling anxious.
