Welcome to SR Rilla, sorry to hear about your accident and job. A lot of us have done things we regret because of our drinking, but that doesn't mean you can't move forward and live a good/productive/happy life.
Staying sober is THE most important thing you can do first, above and beyond your job or car or anything else really. 6 days is a fantastic start, but it will take time to make positive change. You'll find a lot of support here and lots of information about all the various plans/programs that others use to help them get and stay sober. For some, SR is even their main support.
