Ok so we have changed our locks on our home so that our 34 year old son cannot enter. He has been sleeping different places. Naturally it makes me uneasy to think of him and where he might be staying. He has only been out of our home for one week. The reason I am writing is that he works nearby and came by today to eat lunch. He has started a new job and seems to be having issues with coworkers. I really want to know if he has taken something or appears strange...I don't know. He started taking drugs at age 17. Is it possible that he has damaged himself with drugs or do you feel he is taking something. He can always get a job but at some point he messes up and unemployed. I could really use some feedback from those of you that are or have experienced this. Of course holidays are usually hard for all of us.
