Welcome to HCM
I understand your concern.
Your father passed away just a fortnight back. You seem to be having grief period.
after seeing your fathers fate and then death might have created the anxiety in you.
Upto one extent such things are very normal in human life.
Deaths happen in everybody's life, and everybody learns to cope with the stress
and aniety arising therefter.
For some it my take a week and for some it may be months.
But the anxiety has to be subdued, it is the requirement of the body.
Just rrelax, know the reality, know yourself, relax.
Do some relaxation techniques
for a month and you will be OK.
If need be, consult a psychiatrist
Wish you speedy recovery.
