Welcome to TTL. I hope you will like it here and find all support you need. Two kids and a workaholic? You sound great!!
I am sorry for you depression, bipolar and marriage that is failing, but who knows? Maybe it gets saved, or maybe you found another love in your life. Anyway, i am looking forward to seeing you around. :)
P.S. Please dont attempt suicide anymore, you created two beautiful human beings. Thats more then good reason to stay alive and keep fighting.
I started rambling too much, welcome to forums.
