Hi,
Thanks for writing in.
Your symptoms seem to be due to excessive anxiety bordering on panic attacks. I would suggest you to learn
some self relaxation exercises like breathing exercises and meditation. Make sure you are physically active
and at the same time get a good night sleep of at least 8 hrs.
You can also take a mild tranquilizer like Alprazolam at night after discussing with your PCP. Eat healthy and
maintain hydration at all times. You can also get a cardiovascular exam done if not done already.
Take care!
