Hi KN and welcome.
I am glad you've found us, though sorry it is due to your anxiety challenges.
What have you done thus far for treatment? Medication and/or therapy are the two most common and effective options to discuss with your doctor.
For now, checking out our Resources at the top of the main forum page here for great self help material to work with. We have links regarding depersonalization there as well.
Keep talking with us too , if you find it helpful. We do understand, care...and support is key!
Talk soon,
Scaredy Cat
