Once when I was manic I climbed a mountain... no safety equipment, and bad shoes. 4000 ft doesn't seem like that much until you are looking down with your feet barely footed on a ledge... I really do not recommend looking down, thats when the panic set in.
I showed my nephew some pictures, and he put it simply "uncle chris your crazy" which I guess means a lot coming from a 6 year old.
I wish I felt like that again.. I was in such a high spot on every level... to bad that high ended up in a near suicidal depression.
I think writing is a bit safer

. I hope you start feeling better.
