Hi,
Thank you for posting and sharing your story. I can understand that you feel at the end of your tether, as dealing with your wife’s alcohol and prescription drug addiction must be very stressful and emotionally draining.
You sound like you could do with some help for yourself, so maybe you would like to contact us at The Icarus Trust. We are a charity that supports those people who are living with the impact of the addiction of a family member or friend.
if you contact us we would put you in touch with one of our experienced and trained people. You could talk with them which may help you to see a way ahead.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope that this helps. Good luck!
