Depression...just because "it" doesn't hurt like a toothache doesn't make "it" less of a danger. Creative people can sometimes have very dark periods and it can cause some really bad things to happen.
My friend Craig Zarkos was a phenomenal drummer, dad, friend and creative peer. He took his own life last month, and no one knew he was hurting so badly.
So if ever you are feeling that it's just hopeless and there's no one to talk to, there's always someone willing to listen. Just say the word and you'll get an ear. We got to look out for each other in this world.
