As the parent of a child battling depression I can tell you this, it would break my heart to think of him going through so much pain alone.
As to the scars, it is initially scary when a doc sees them, but my doc was actually very supportive. It gave me a sense of relief and security.
One more thing from a parents perspective...trial and failure are part of the learning process...all I expect from my children when they make a mistake is that they learn from it and all I want for my children is for them to find happiness - no matter where it is.
Hang in there...times are tough right now...you are stronger than you know!
