Hi, from your description of symptoms it looks like that you are experiencing panic attacks for which you need to consult a psychiatrist. However we need to rule out causes of discrete anxiety like Thyrotoxicosis ,cardiac causes of anxiety or even pheochromocytoma if you have not undergone a medical assessment for these symptoms ...

From your description it seems to be ‘panic attacks’..... This can occur secondary to some stressor and sometimes without any stressor.. Still further evaluation required to decide treatment plans

It seems you are on medication &Still facing anxiety issues with physical complaints. One need to address the cause of your sufferings through detailed case taking & Accordingly giving medicines to deal with both anxiety &It's physical accompaniment.

Yes you seem to be having an anxiety disorder.  There is not always a reason for anxiety attacks. It is very much a treatable condition. We treat with medications and psychological therapies .
