@life1, it is good that your son is seeking help. Did you see the helpful replies from @momof374 and @briarrose?

I know that feeling of being helpless and giving him his space. You want to do something. When my daughter was a teenager, I found it helpful to join a parent's group to learn I was not alone. I also read the book "Parenting a Teen Who Has Intense Emotions." There are resources and supports out there to five you tools to know what to say and when.

I realize your son is older than my daughter was when I needed support. Have you considered a parent's group counseling or talking with a therapist?
