...I sometimes feel at a loss to help him. I've never been through this
just continue to let him know you will listen to him whenever he wants for as long as he wants and as often as he wants.
Also, call him randomly and often. So many times, in my worst moments, I would just need to talk to my brother or a friend again and I would think, "I gotta stop bothering them, I do this too much, they must be sick of all my repeated ranting."
And then I would think, "But since they know I'm in pain it sure would be nice for them to call at times like this. I just wish someone would call...right now."
Peace,
Gardener
