This will seem like an odd thing to post-- I certainly didn't expect this video to have any connection to PTSD and hope and support-- but I found it surprisingly touching. About halfway through the video, maybe a little later, he talks about projects he's started on the internet to foster communication and connection between people. He then mentions some personal requests he's had from people to write songs addressing fear, or addressing sadness and anxiety. I won't spoil the surprise-- I'll just say that he does it in a pretty touching, amazing way. I felt really good at the end of this video.
