Lets see where he is. As someone who has had experience of MH issues, (both me and my late partner), once you accept it as normal, understand why it happens, and learn to deal with it, this thing called clarity arrives. The fear goes, the reasons become understandable, and you can junk the meds that really do not help without ^^^^^^ being arrived at. You also know when an issue is brewing.
Only he knows where he is. But in my experience, baring your soul to the public, or in my case, to friends and family, is a pretty significant step after the many steps he/we took in private.
