Worried I will never be rid of the anxiety
You're anxious that you won't stop being anxious, which is like a dog chasing its tail! Stop chasing your tail and as
@Sita suggests - do something positive to reduce your anxiety. For example, listen to and follow the advice of Dr Claire Weekes - there's an audio book of hers called
Freedom From Nervous Suffering (it's available from the Amazon website). For encouragement read how doing exactly that helped
@Diana-M with her anxiety regarding leaving her house after many months of being house bound, here:

Whatever form your anxiety takes, however it manifests itself, listening and, most importantly, doing what Dr Weekes says to do, will help you break the cycle of you chasing your anxiety tail. You could also meditate, do slow breathing exercises, take up tai chi and/or go for a daily walk if your symptoms currently permit and if they don't currently permit, imagine going for a walk. There is no time like the present - do something positive
NOW to start getting you out of your funk, no matter how small, and then build on it.
