I too can empathise with you, I know how utterly horrible it can be. It's wonderful to see that you're overcoming it to do something like this. I can imagine you'll end up being an inspiration to a fair number of people on here, both with your ride and how open you are about it all. It helps people be more aware and more likely to get help when needed if we can all be open about it :)
Hope the trip continues to go well, I'm really looking forward to reading up on all your exploits!
