One temptation when going through a high degree of stress, is to entertain extreme thoughts. 

The temptation to flee is called a "geographic" in AA, which is moving out of town or out of state to escape troubled relationships or avoid responsibility.  The impulse to pick up and leave may appear in your mind one day offering a quick fix to your problems, but please remember that wherever you go, there you are.  And if you're addicted to drugs or alcohol, you're still addicted, but now you don't have the benefit of family and friends. You can make changes locally.  One great idea is to attend an AA group and talk it over with a few others.  Another great idea is to search the internet for a recovery friendly church.
