The young man has been enabled all of his life with every wrong choice he has made. From the parents accepting his excuses to the friends and family covering for him, sometimes just to keep him from making an outbursts or disrupting their lives. Everyones actions whether we know it or not has a ripple effect on other peoples lives. Sometimes the ripples are good, sometimes not so good. Obviously from what you tell us the young mans ripples or problems are now becoming more destructive. It's hard to let your child fall on their face to learn a hard lesson, but sometimes that's one way of dealing with it. Stop bailing them out of their problems, make them stand on their own two feet, encouraging them along the way. Making them accountable for their actions whether they have a "good excuse" or not makes them stop for a moment and look at what they have done.
Hopefully they will ask themselves if that was the right way to act, or has that affected someone else? He's not aware of the wrong things because no one has been bold enough to stop him, making him aware. The problems you have mentioned are psychological problems. We all have went through steps to learn to handle them. He has missed that step. He will not admit to this problem, as most people with any psychological problems rarely do. Even if they are placed on medication to help many of them will stop taking it, saying there really is nothing wrong with them. I would suggest a psych evaluation, but until you are able to convince him he needs one, it will be left up to you as an advocate to help him along the way. Sorry to say it's very time consuming and heartbreaking. That's why we need a specialists, a third person to play the bad guy and tell us the things we need to hear. They usually listen to a stranger before they do us, and with a doctor involved they can't use their emotions to control them. A specialist will find out what triggers these behaviors, only then can he change.
Hope this helps and you can find the help you need. writer 52
