I am sorry to hear that your friend wrecked his car, w0w, but it sure is definitely NOT your fault. He is an adult who makes his own choices and unfortunately, he has a very bad consequence b/c he chose to drive high. And, every addict I know drives when they are high. I used to drive after I went out drinking, and to this day, I am so grateful that I never got a DUI or worse, hit another car and hurt another person. It was pure luck. I don't drink anymore, but I do drive while on my prescribed doses of opiates. Captain H is right, and I look at it as a sign that someone's addiction has progressed so badly that they are unable to use their own judgement that they should wait awhile before getting behind the wheel.
You are a very caring person so I know this bothers you alot. Just take care of yourself until you get through the worst of the withdrawals, and then you can be there to offer support and to listen to your friend. Thank God he didn't get seriously hurt, or worse in the crash.
It sucks that you went to the ER and the wait was so long. When I cold turkeyed in 2013, I got right in, and the clonidine was magical... I was able to make it through the rest of the withdrawals with only insomnia and intermittent chills. I keep thinking you should be through the worst, and then I remember about your benzo addiction. I am keeping my fingers crossed that you get the meds at the ER, and a bed at a detox.
