Go out a lot to the fresh air, preferably in the forest if it has one nearby. If you can't figure out the trigger of fear, hypnosis would be a possibility, or even mystical music. Let yourself fall to the music, it's best to do it on a thin mat on the floor.
Whenever possible, leave the finders dependent on anxiety-solving drugs that make you dependent and if in a crisis the chemistry stuff no longer exists you have a big problem.
I wish you the best to get out of it, the way can be tough, but you will manage to do that.
