You are obviously in a tough situation. Your brother is unwell and your parents are unable to care for him. Based upon the information you have provided, it seems as though there is little that you can do. You can express your concerns to your parents and attempt to give them advice but there may be little that anyone can do.
You might try communicating with your brother, as a way to keep tabs on him but don’t expect much. If he’s actively symptomatic, then he may not be responsive to anyone except perhaps your mother.
The reality is that there may be little that anyone can do for your brother at this time. He is clearly unwell but unless he is a danger to himself or to others, he cannot be forced into treatment. Involuntary commitment laws can be very strict.
It’s difficult to witness loved ones suffer, engage in behaviors that are clearly detrimental to their well-being and to be unable to help them. It’s a very helpless feeling. Unfortunately, many families are in this same predicament.
Call the authorities if necessary, if your brother is endangering himself or other members of your family. You may also want to contact your local mental health crisis team or the community intervention team (CIT), if available in your community. They are trained to deal with mental health crises and can advise you about how to handle your brother.
Finally, you may want to contact or review the website of the Treatment Advocacy Center (TAC). TAC is an advocacy organization dedicated to assisting individuals with severe mental illnesses and their families. Check their website for resources.
I empathize with your situation and I wish I had a better answer for you. Do your best with whatever resources are available to you. Please take care.
