Hello and welcome to Healthcare Magic. Thanks for your query.
I understand that you must be going through a difficult time with your aniety / panic as well as the other physical symptoms. All your symptoms seem to fit into the category of an anxiety disorder. The panic attacks, health anxiety, fear of dying, physical symptoms like palpitations, etc. can all be explained due to anxiety.
It is important to understand that anxiety can present with not only psychological symptoms but also with physical or somatic symptoms. Shakiness, dizziness
, fast heart rate
(palpitations), etc. are symptoms which are commonly seen in anxiety disorders. So, you needn't worry about the palpitations.
Since you seem to be having a lot of distress due to your symptoms, I would suggest that you seek professional help to deal with the anxiety. There are effective treatment options - in the form of medication or counselling
which will help you overcome your problems. So, please consult a psychiatrist
for further treatment.
Wish you all the best.
Dr. Jonas Sundarakumar
