I am sorry your family is going through this and I am sorry your brother is in so much pain. Unfortunately sometimes you have to let an alcoholic/ drug addict hit rock bottom. ( this is assuming he is still abusing these substances) Supporting a destructive lifestyle will be far more harmful for him in the long run. In regards to work, let’s face it, who really wants to go to work. If it is a job you love, maybe. Speaking first hand, working with anxiety is no fun so I empathize with your brother. I would suggest looking up careers that will be less stressful for him. I heard medical coding is good for people with mental health issues. I don’t have first hand knowledge of it yet but hope to soon! Maybe he could take a job where he is working with video games. If your parents are going to help supplement his income, maybe reward good behavior and not the bad. So like no support if he relapses and/ or quits his job. If there are no consequences for poor life choices, where is the incentive. Clearly it is not for the pride of standing on his own two feet. In regards to the bpd, there is a set of skills he can embrace. Marsha Linehan developed Dbt skills based off her own struggles with bpd. He could look up YouTube videos on it or buy a book. If his attention span is not there, the videos may seem less intimidating. He is most likely learning these skills anyway in the outpatient program. One last thing. I struggle with SI too. I was recently put on lithium. If he is not on it, this may be something they could consider trying. I would ask the psychiatrist about that. I have also been working on being present and getting outside my head by paying attention to what I see hear feel taste and smell This has helped some. Your brother may be using video games as an escape but they can be addicting too.. Good luck with your brother.
