Hi, thank you for using health care magic.
I can understand your concerns.
First you should get blood pressure,Hemoglobin,Thyroid function and vitamin B12 checked. If this all are normal then there is increased possibility of anxiety disorder. Anxiety disorder have various type for diagnosing it accurately you need to visit psychiatrist as mental status examination is needed.
Anxiety disorders are treated primarily with the help of SSRI medicines (like sertraline , escitalopram, etc.) and use of benzodiazepines (like clonazepam, lorazepam,etc.) . Cognitive behavioral therapy which is a psychotherapy is also helpful in anxiety disorders.
Hope this will help you.
Regards.

Dear
Welcome to HCM
We understand your concerns

I went through your details. I suggest you not to worry much. If you are suffering from the dizzy feeling / light headiness for five of six weeks, you should consult a physician and get proper treatment. It could be nothing and related to some simple physical conditions. But it is always better to get yourself confirmed.

Over and above, you are already started feeling anxious about it. Such anxiety could lead to obsession. Obsessive thinking about the symptoms can lead to symptoms appearing again and again more anxiety.

Once you know that there is nothing to worry, your anxiety feeling stops. Please confirm with a physician.
