I'm so sorry things are still so unstable. I wish you all the very best. And I thank you for the valuable service you're performing by shining a light on the problem of the mentally ill and homeless. It isn't easy to find solutions for people with mental illnesses like your son has, but as a society we need to grapple with it. We can't do that if we don't see the problem from your perspective, the perspective of a loving family member.
It's too easy otherwise, I think, to simply dehumanize people and wash our hands.
