Michelle, we are all very sorry for what has happened in your life.
At the same time, please do not stike out at people here. We know a lot more about oral cancer than we do about relationship problems, but that does keep us from feeling bad for you, and no one has suggested that you take your difficulties elsewhere.
Nobody can fault you for what you might think, but please do not insult the people on this forum who have been through some really tough times themselves.
I wish you ease in your heart and that you soon recover your equilibrium.
