Your daughter still has a long way to go in her life. If you check out now, it will have a devastating effect on her life that could be permanent. If she ever starts thinking about checking out herself, she will have you as a role model. You don't want that.

If you check out you are going to deny both of you the chance to know each others as adults. That is something you aren't going to want to miss.

Here his how it affects survivors, especially sons and
daughters (from Salon):

Dear Cursed by Legacy,

Your letter made me sad. I get sad when I hear how parental suicide reverberates through the years. I get sad when a person like yourself tries hard to live a decent life but that life must be lived in the margins of trauma, in the echo and shadow of that early blow. I get sad about the terrible theft that is parental suicide, the hollowing out of a child’s emerging self. And I get sad about what may happen if you continue coping with this in the way you are now.

According to a 2010 study, “Those who lost a parent to suicide as children or teens were three times more likely to commit suicide than children and teenagers with living parents.”

You don’t want to leave a destructive legacy.
