Acceptance is a key to our anxiety symptoms. As Cuchculan mentioned, know that what you are experiencing is not going to harm you. Do not fight or fear the feelings that your mind has created. If you do, this just creates a loop of fear feeding fear, thus increasing the symptoms of anxiety. I know that this is not easy to do, but the mind trained itself to display our anxiety symptoms, and it can be retrained to accept them which will break the loop and diminish or relieve the symptoms. Reprogram your negative thoughts with positive ones. This is one of the strategies of cognitive behavioral therapy (CBT), which is something you may wish to add to your anti-anxiety tool chest. I am scheduled to begin CBT in the next two weeks.
Do not beat yourself up over having to restart medication. This is by no means a sign of weakness. For many of us, anxiety/panic attacks/depression are chronic conditions that have an organic component that requires medication, no different than a person with diabetes needing to take insulin. I have been on a anti-depressant for over four years now, and will most likely need to be on one the rest of my life. I consider myself fortunate that anti-depressants are available, as it wasn't that many decades ago that these medications didn't exist.
Give yourself credit for each positive advancement you make, regardless of how small it is. Remember that we had to crawl before we could walk, and walk before we could run.
The very best to you, Bubbles!... Chuck
