Whether yes, or no, bear them in mind, now check below:

1.) Fever? (Oral temp, please. Check after > 15 mins after drinking hot/cold beverage, longer to wait for temp to normalize for most accurate reading; best time is first thing in AM upon waking).

2.) Lethargy? Unusual tiredness that comes and goes, then comes again. In other words, what is your energy throughout past three weeks?

3.) Sweating with or without chills? Night sweats that you normally do not have?

Wrote down the answer to 1, 2, & 3. Call local healthcare if either one item of the 1 to 3 is true, and tell them those data.

Lastly, if anxiety is ongoing, look up "breathing triangle gif" on Google, and try to help getting some sort of control.

If in doubt, contact a healthcare provider/hospital.
