I have found the pills did nothing expect make me sicker. I have tried very hard to self manage myself but it is very hard. My anxieties are medium most of the time and high every now and again. It does ruin your life no doubt but you have to try to work around it. My physc sessions were not that useful however the one thing that I found really good was the link between anxieties and depression. The brains serotonin levels go down as your anxiety goes up. You may know this, so its a balancing act. So the way to increase serotonin levels is through natural causes not pills which only balance the levels.. There is list of things that do including being happy with yourself, which is the first thing to do of course. But also regular exercises, discussions with other people, eating nice food, etc. There is plenty of literature on this. All the things that make you feel good. I also do meditation sessions and there is a really good one on line app called 'Headspace". Its great. Also yoga sessions. Learn to do the breathing techniques, it really works pretty well for me and I had never done meditation before I started getting these attacks. There is a lot of literature and help on these subjects. If there is a particular thing that is causing problems you may need to fix that also (if possible), but always hard. I still have these problems but working on them your self I think is a better option than pills. If it is too extreme you may need the pills as well but still work on the tasks I mentioned above..
