Hey there,
So sorry you're going through this. I'm 37 and was prescribed xanax about 8 yrs ago. It was the only med that helped me. I've actually never heard of xanax contributing to dementia but I assume the docs know. I have found that my psychiatrist and primary care doctor never agree! Since I became pregnant a few months ago I tried weaning off and it is incredibly hard. I had good days and rotten days, the rebound anxiety is terrible. I'm not 100% off but at least I did the best I could. Yes, CBT can do a lot of good. I do find or sudden attacks of anxiety, the xanax helps a lot, but if you're at a point where you can let the anxiety pass, it will go away. I think CBT will be a great thing for you! You may learn things about yourself you never knew before. I found the source of most of my anxiety issues which is very helpful. Hang in there, and yes try CBT! If you dont click with the first therapist, try new ones until it feels like a good fit. Good luck, you'll be fine!
