How to stop drinking and contribute something to this world?

You say leaving the bar drunk is pretty normal for you – is it also normal for you to get into your car and drive whilst drunk?  If so it’s hardly surprising that you have finally hit something or someone.  You are now faced with the truth about your drinking – it can harm others.  And it can get you into a lot of trouble. 

It’s often when an addict hits a crisis point or is backed into a corner that he will start to make some decent decisions about his life.  I’m glad you have done that.  Now it is up to you to follow through with those decisions.  You could begin with contacting the police to explain what you have done.  Yes, you will be admitting to a crime, and you will be handed the consequences.  That doesn’t sound too attractive but it would be the beginning of being honest with yourself and with others, being accountable and taking responsibility for your actions.  Your second task could be to enquire about rehabilitation centres.  Find out if there is a Christian one near you, and if they can take you.  If not a Christian one, a secular one will do the job just as well.  Lastly, go to church.  You might be amazed at the support you will find there.
