Paulos,
I am so sorry your feeling like this but I am also so proud of how far you have come and you are channeling yourself toward positive things, reading. That is wonderful.
Make an effort to stay focused on what's happening now. What do you see, hear, and smell? How do you feel? Truly be 'present' in the moment! That will help you keep the anxiety down.
The miracle of your existence calls for celebration every day.
Hugs
Kitt
