Dear Welcome to HCM We understand your concerns. I went through your details. I suggest you not to worry much. You know the cause and effect. You are already sure that the anxiety is caused by birth control pills. As your gynacologist said, birth control pills do create such a condition. That is it. Once you stop it, the condition should be cleared within a week or so. You are having it again and again an panic attacks because you are apprehensive about the medicine side effect. Leave it aside. Medicine side effect cannot go for more than a week or so. But worrying about aniety should increase anxiety an give you panic attacks. You need behavioral Psychotherapies which I can provide you if you come up with a premium question with all those details about you.Alternately you can visit a psychiatrist for medicinal treatment. Hope this answers your query. Available for further clarifications. Good luck.
