When I was in my early 20s, I tried to kill myself. I can emphasize with your son. Decades have passed since my attempt, and I'm still alive, but also still depressed.

Chances are, the family dynamic that you are all facing is not a healthy one for any of you. Your idea to send your son to Florida recognized the fact that you needed a vacation from each other.

If you can think of anyplace that your son can go to on a long-term basis to be in a different environment with different people, then the solution may lie there.
