Hi, my advice is go to the doctor, your health is priority.
It could be due to high emotional stress due to the fact you mentioned you have lost your mum and many other factors.
Sorry for your loss .
You also mentioned you have recurring ear infections you might want to get that infection treated right away as ear infections not treated promptly can cause life threatening complications, like mastoiditis which is an infection that has spread to the mastoid bone which could lead to meningitis, brain abscesses which is dangerous .
Please get treatment Otherwise you might have a treat to your health worser then coronavirus.
I meant threat not treat in last sentence .
