I like the 5 actions, and the fact that I will fail at them before I get them right, that gives me HUGE permission to be human. My son is an adult - he is almost 40, and has only lived on his own for 6 months. He cannot get along with other people - friends, employers, family, store clerks, people at the gas pump, other drivers - he is down to me and my husband, who is not his birth father. That makes it really tough - he cannot keep a job, it always ends up in a blowup and he quits or walks out. Family members are cordial to him if necessary, but that's it. Friends - nah, those went by the wayside long ago. He does have a passion, and that is cannabis - grows it, smokes it, spends hours each day taking care of his plants, who cannot talk back to him.
Okay, so the advice changes a little since your son is out of the home. That actually makes this 100x easier on you because it doesn't have to be a daily blowout session at home.
Think about what you said. Your son:
- can't hold a job
- can't get along with co-workers
- always gets frustrated and quits
- doesn't have any friends
- can't get along with anyone
- is tolerated by relatives
- is passionate about marijuana
What part of any of that is a "you problem"?
The truth is, none of that is your concern. But here's the problem. Because he fails at all of that, I'm assuming that you're supporting him and still accepting his abuse. That's the part that has to stop. He can do whatever he wants because he's responsible for himself. But he can't bite the hand that feeds him and expect for it to continue. That's the lesson you must teach.
Here's the other part of that. The more he realizes that his attitude isn't doing him any favors, the more likely he'll be to get mental health help. As long as you're bailing him out though and showing that life doesn't have consequences, the more he'll take advantage of everything in life and create destructive patterns. You help is actually enabling him to become sicker- you must see that clearly. That's the only part of any of this that's actually your fault.
