I feel you man, but you don't have to beat yourself up. We are wired to survive with strong SI. Some people are able to do it suddenly out of no where, almost impulsively, while others do it after a long period of meticulous planning and attempts, so it's a really personal experience. Maybe you're not ready yet. Maybe the moment wasn't right. CTB is not a race, not even a marathon, this is something beyond my comprehension. The choice is and always will be there. There shouldn't be judgement on such a powerful and personal thing, not from you and definitely not from anyone else, so rant on here and get your bad feelings out and feel better.
