Thank you so much for leaving this comment, @d00k13. This is not an easy topic, but so many have the issue to one degree or another. Caleb can do really well when he applies certain strategies he has learned and even counsels others to help them get through it too. I read some of his posts about 1.5 years ago and I was so proud of how he was doing with it. But it's not a smooth path and things have just spiraled down hill since then.

He has said the same thing. It's the comfort level and learning how to stay comfortable that is a big help. Once you start running and panicking, it goes downhill - especially if safety does not come soon.
I hope he does find someone something. He's had two mentors and both have died tragic deaths in the last five years. This does not help, but maybe the third will be the one who stays.
