Anxiety is rampant.

Hey everyone, I’m currently on day 5 with Flu A. Most of the rough symptoms are gone (fever, muscle aches, lack of sleep etc) but starting yesterday I have just been in pure panic mode, maybe even dissociation. I can’t tell if it’s just brain fog, dizziness, whatever. But it’s miserable. I’m also developing cold sweats at night now but have no fever when I wake up and my congestion is going out of control. This is the worst thing I’ve ever dealt with, but it’s not the sickness aspect. It’s this damn anxiety. I have GAD and have been on medicine for years and had it completely under control and it feels like I’ve lost all progress I’ve ever made right now. I guess what I’m searching for is if any of you all had similar experiences with my time line and if it got better? Thank you all
