If you"think" you have anxiety then you need to see your Doctor for a diagnosis and a treatment plan. Not many on this website can really help you I'm sorry to say. Make a Doctor's Appt. And let him/her treat you for it. That's what I had to do. Quite successfully I might add.
Try not to be your own doctor. When you do you will have a foolish person as a patient. I think Rooster's suggestion is your best recourse.
Real anxiety syndromes and disabilities are not something you can treat on your own .. Because it not just about choosing to feel that way. It is a chemical imbalance that can be medically treated by a doctor. If you feel this is a condition that is causing problems in your life, then see your doctor.
