My younger daughter slept with my older daughter's husband. Do I tell her?

Tell her. It might help if she understands why you did that. I mean, I understand.

You didn't want your wife to murder you. If anyone else can't understand that, they clearly weren't paying attention. See what happens.

It might help your relationship with her and fix your life a little.

Well... One month ago I was depression changed to mood energy and appetite too, bipolar sympotms seems same me since three weeks ago and but sleep with 6 to 7 hours and also wake up every hour or two hours.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
