Are you seeing a professional for your anxiety? I know that i was really lost when I tried to deal with it on my own. It was quite overwhelming. I know there are varied opinions about medications for anxiety but there are some very useful ones out there that may benefit you right now. It might be worth looking into them. Also there are the non medication routes such as yoga, meditation, mindfulness, therapy, breathing techniques, etc.... All of which are beneficial.
As far as my anxiety goes I am not sure that it will ever be completely resolved. I think the best I can hope for is to learn how to live with it and not let it rule my life. Unfortunately between the bipolar depressions and the PTSD it makes it difficult to work on the anxiety issues without triggering another dangerous depression. But all one can do is keep putting one foot in front of the other and not give up.
Take care and I do hope you find a solution.
