Hi,
Welcome and I'm glad you found us!
Yes, detoxing from alcohol can be dangerous. You can always go to an ER if you have concerns.
The Salvation Army offers from rehab to anyone who wants it, so maybe you could check out your local office and get some information.
I think most, if not all of us here, had to make very difficult decisions in order to recover. I couldn't be around people who were drinking alcohol for a very long time.
