My brother is a compulsive liar who has been diagnosed at least once with ADD and still has had no substantial help. He is an adult, a caring man and a great father. But he has bankrupted his family by lying about getting jobs etc. His wife is an amazing woman and we siblings have no idea what to do.
I will be following this thread to see if there are any suggestions for you that might help me, since we appear to be in a similar boat.
