It sure does help to talk with others, just don't expect anything from them when you do. Some people are better at taking this kind of story than others, so if you see someone shutting down a bit, let them know it's OK. They might need your support in hearing it as much as you need theirs.
Also don't share the story for the first time when you're driving. The first time I shared my story was when a friend asked me "What's up with you and your dad?" i was driving us home from the beach, and i started telling him, and it was like the light went out of the sky, really strange. His response was awesome, but I shouldn't have been driving.
Best wishes! This is an exciting part of the journey.
