My son is 18 now and couldn't finish HS due to anxiety and depression. (He was homeschooled for the last 3 months.)It is still day by day but we are trying to help him the best we can. I am right there with you on the concern for post-high school independence as he wants to go to college but is having trouble with everyday life right now so we are not sure how to proceed. We are getting him as many support services as we can and I would recommend looking into what is available in your state if you have not already. We have some things like assisted living and job shadowing for people with disabilities so there is hope of an independent life for our son though it is very hard to qualify for the services. I live in NY state so I am not sure what FL has in the way of services but hopefully there is something there for you to tap into. Good luck and stay strong.

i have a home therapist through my doctor and also you should be entitled to an outreach worker you can be referred by your dr or social services will have information about residential care were they teach them life skills

I have. We tried hospital home bound school. They worked for a couple of days. When he says he wants to go to school that also lasts just a few days. I believe the school system is trying help but he doesn't respond. Did check out agencies but they don't have any answers.
Thank you for your input.
