Have you tried contacting NAMI, the National Alliance on Mental Illness? They are accessible online and have chapters in many cities. They offer information, guidance, support and resources for you, the parent ,as well as your son. I've taken their parent course and found it helpful. It sounds as if you need options, advice, support, information, resources ......and help.....perhaps NAMI can steer you in the proper direction, it's likely they've dealt with similar situations or can direct you to who has.
Here is the contact info:

This is hard stuff. While you're negotiating yourself thru this process, please make sure you are amping up your self care, it's very easy to get depleted and depressed when all of our energy goes to our troubled kids. Remember, you matter too.
You're not alone, we're glad you're here.
