Oh, wow, what a really unhelpful hotlines (heavy sarcasm alert). I only use to call them when I was between counselors and didn't know how to get another one. I once actually went to training to work on a hotline but couldn't deal with that :-)

It's awhile until Thanksgiving, something might change? Don't give up your hold on the end of that rope yet, as the really lame cliche goes, "tie a knot in it and hang on."

What would help with making you feel better? I think were I in your shoes I'd work at "not caring" about my sisters this year. Do you have any nieces/nephews? I use to have mine to my apartment and even took my oldest one to university with me when I was doing summer school once and all that helps a little now with when I see them with their children at Christmas. Things truly get better the older you get.
