Not sure if I should switch back to Xanax

I have been on Lexapro on and off Xanax, Ativan and Xanax as needed for over 25 years. I was doing great I retired. We moved to Tennessee change is not good for me so I knew I would go through some anxiety, but six months into the move, my husband was diagnosed with small cell carcinoma of the lungs. It seems that my drugs are not working for me. I guess I’m on overload. I was wondering if anyone has gone back from Ativan or clonazepam to Xanax since it’s faster working please let me know and press for my husband are always appreciated. Thank you.
