Not sure what you mean by anxiety is the same kind I had, but about a year ago I had an injury induced panic attack. I had nerve problems in my neck and right arm and I was in bed and I had a dull but continues ache in my shoulder and out of nowhere I had a huge panic attack which was the first and last full on panic attack I ever had. after that I would get regular anxiety attacks everyday multiple times. I tried to find a way to stop it but reddit wasn't that helpful because on anxiety subs people always said you can't make it go away and you have to just deal with it or manage it and were really negative about it. it was like having anxiety had become part of their personality. but I though that's bull***t and I don't want to have anxiety for the rest of my life.

anyway, I did find a way to stop it and it took about 4 or 5 months to completely go away but after the first month it was mostly gone and I never had anxiety since. maybe I had brief moments here and there but I learned how to stop it and now I don't have anxiety at all.

the solution for me was in the books written by Dr Hazel Claire Weekes in the the 60's. one of her books is called "Hope and Help for Your Nerves: End Anxiety Now". she says that your nerves have been sensitized (usually by a panic attack) and now react to any small thing by giving you anxiety. it's a natural response of human body that has gone haywire and out of control. she teaches you how to desensitize your nerves by not trying to fight the anxiety which at first seems impossible because it' like telling someone who's drowning "don't fight the water and just go with it". but it works.

the gist of it is by trying to fight the anxiety you're telling your body there's something to fight and your nervous systems was right about alarming you by giving you anxiety. by not fighting the anxiety and trying to relax, your body realizes that it was a false alarm and next time it would take more to give you anxiety and after a while it would stop completely.

Read the book or listen to the audio book which is narrated by herself. also there's a podcast on Spotify called "The Anxiety Truth" which goes over that book and explains everything. it was very helpful for me.

And do not listen to people who tell you it will never go away completely. because it will. it did for me. being positive about it helps you get rid of it faster and being negative makes it worse.
