Wow - there are some really, really quality responses here. Thanks so much everyone for your thoughts. Now if only THIS were my off-line community ...
On reflection, I'm realising that some of what's happening here is part of the the natural flux of my life - I am at a point of change - just out of my twenties, moving back home after 8 years as an expat, going back to school. Expat life is strangely transient anyway - people come and go - so the old-timers tend to form ... interesting relationships. In a way I suppose BB kind of taking over my life is part of the process of moving me forward, and is intimately connected to the decisions I've taken about which way to go. I guess ultimately these relationships were destined to be temporary anyway - I have some forever ones, but those ones aren't at question here. Maybe it's just hard to come to the end of a microcycle ...
You have a really good point, circusgirl, about what people would say were it another sport. I think for the large majority of people, BB is all about vanity, and maybe for many BB's it IS about that, but it also goes SOOOOooo much deeper - and this is something I just absolutely cannot explain to someone who hasn't ever pushed themselves beyond pain, beyond thought, beyond anything they thought their bodies/minds capable of. I used to try and express it, but now I just don't talk about bb'ing anymore with most people. MS, you're right - if one gets too ... erm, excited talking about it, they start squirming, and one ends up feeling stupid. Now I just rattle around in my own head mostly, driving myself crazy.
Spatts: "I live my life like this, if you want to be part of it, work with me. Otherwise, ta ta. I guess I'm saying I'm a heartless, and selfish, but without the guilt." See, this is what got me into trouble in the first place. Others would like ME to adjust for them as much as I would like THEM to adjust for ME. But the adjustments possible on a comp. diet are miniscule compared to how the average joe can adjust, thus the friction. I appear heartless because I won't adjust. And while I don't feel guilty about it, I do feel unfairly accused, and sad that that is the perception.
BUT, fuck it, that's the way the cookie crumbles and I'm in this 100%, so .... on to new frontiers.
