I think that sometimes, with some people, providing support to them would mean to state the obvious.
Like I said with that weight loss class at church, often I'd see a whole lot of so called "support", yet no action. Hardly anybody was changing their diet, and they definitely weren't exercising. Some people were still eating exactly like they were before, including drinking several cokes per day, then they'd come in and would be looking for "support" during the meetings. It makes no sense. I mean, come on, if you go to a class and want to learn how to lose weight, you should be able to handle somebody telling you to knock it off with the cokes and walk more instead of wasting time.
Anyway, in that situation, are you really providing help and support if you just let people cry about it even thought they're not really changing anything? That kind of "support" doesn't do anything, it's just a waste of time. An hour and a half per week to be exact.
If people really are looking for help and support, I think they should be prepared to hear things that they don't necessarily want to hear, and thoroughly consider them. Otherwise, they're probably just looking for a shoulder to cry on about their problems more than truly trying to do whatever it takes to lose weight.
