Have you been diagnosed or seen a doctor for your anxiety? If you haven't, you should see one and the doctor or psychiatrist should be able to find a medication that works for you.
Chest pain, numbness......these are signs of anxiety. You do not have a heart problem if this pain is caused by your anxiety.
In most situations, people with anxiety have to be diagnosed by a doctor as having anxiety...meaning that tests have been done to make sure that there is no real medical evidence of what is causing the symptoms you have, and that they are caused by the mere fact that you do have panic attacks and a disorder.
