Something that you might want to look into is going the spiritual route like I did. Many, including some in the medical field, consider panic attacks as a great tool to awaken. To awaken means the end of suffering. All spiritual teachers, best seller Eckhart Tolle, agree that panic attacks are the most immediate doorway to awakening. If the person uses a panic attack or some other form of intense suffering as a way to surrender and not fear its powerful body-mind energy surges. Just feel the energy surges without giving them a story. Just let the energy go through you. Trying to contain and resist them is what makes them reoccur and get stronger and stronger. Just consentrate on the body sensations. You won't die. They won't kill you. Each time they come, they will lessen and lessen. The trapped energy created by the scary stories we have accumulated will start to dissipate. A good advise is to stop thinking so much, and start to meditate. Any way, I no longer suffer from these and i am thankful to them because they started me on this path of being awaken to end all suffering. I highly recommend a guru called Mooji. He's someone out of this world. Check out his youtube video"From full panic attack to full power." See the other two he also has on panic attacks. You will feel so much better after listening to him. Eckhart Tolle is also great. A panic attack was his doorway to enlightenment.
