Please help!!!!

History:

F19. I have preexisting severe LPR and GERD. Mild preexisting anxiety, depression and hypothyroidism. I also have small gallstones, slightly high liver enzymes and low WBC and neutrophils from extreme weight loss (90lbs). My lymph nodes are enflamed frequently. I’m slightly underweight and mildly malnourished, no longer menstruating due to this.

I was heavily exposed to Covid 3 days ago. I was masking but used a kn95 (my n95s hadn’t arrived yet).

Symptoms:

Today I ate my typical safe foods (russet potato, rice Chex and a little oat milk) and I started having debilitating neck, chest, head pain/pressure. My upper abdomen was burning like hell. Extremely fatigue and tingles across my body. Slight cough and runny nose, which is consistent with my LPR. My blood pressure was slightlyyyy low.

Then the anxiety hit. Crippling panic with impending doom. I don’t get this hardly ever, unless I’ve eaten something BAD for my stomach. But I had eaten foods I consistently tolerated well.

I took Pepcid 20mg, which I had taken in the past, and it didn’t seem to help.

Then sooo much depression. I’ve been crying basically non-stop since. I’m still very anxious but doing a little better, I haven’t eaten anything in a couple hours now. I still have all the physical symptoms, accompanied by extreme fatigue and weakness. No fever, but my forehead and arms/hands feel very cold.

Question:

What do I do?! Could this be Covid?? I hear people get lots of anxiety and depression with Covid, but this would be BEFORE peak symptoms hit, which terrifies me. Don’t people usually get the anxiety depression symptoms during the peak or post Covid?

Has anyone had this before? Is it possible it won’t get worse and it’s a pre-Covid thing? What helps this?!? I have Valium but I’m nervous to take it since I don’t know what’s going on…
