Alicia, have you discussed the anxiety attacks with a doctor? There are plenty of medicines that would help you with this problem.
i didnt mention it in the other posting because the anxiety attacks strted happening way way after the blackouts and the anxiety attacks only really happen every once in a blue moon and its really scary cause nobody around me really knows what to do
You need to see the doctor about this and have him recommend someone for you to see. Hyperventilation can cause a person to pass out because of a lack of blood flow and oxygen to the brain. You did not mention this anxiety problem in your other posting here on the forum. This may be the reason for you passing out.
I get the shakey bit I'd go and see your doctor :)
