People usually don't promote a level of righteousness higher than the standard they live themselves... Thinking back on my 'control' post, I know there's nothing I can do about it, but my W's new 'support system' is full of divorcees with multiple kids and nothing but angst for the men that betrayed them.
I'm not going to let it get me down, and I have some 'support' that gives bad advice too, but some people are more influential than others in this sense.
Just remember, close friends and loved ones are great to have for support, but they're every bit capable of giving you advice worth less than the trash you take out on Thursdays.
