Hi, welcome to Healthcaremagic.com,
This is purely an
anxiety condition but if it is not controlled in time you can be a victim of another serious physical disease like
Insomnia,
Hypertension cardiac trouble, Acidity leading to peptic ulcers,
depression etc.
As u say that your sugar is under control so be positive and try to maintain it.
Also try to become relaxed, do something which gives u happiness & pleasure-Like Driving, gardening, listening music, relaxation exercises, outing with your family.
this will certainly reduce your anxiety and u will feel better
you should consult to a homoeopath also, he can prescribe u medicines which will help to change your present state of mind to positive thinking.
Take care,
