Sigh--you have your hands full! Having a handful of really young children is a challenge even with a healthy marriage. Throw in a lot of emotional turmoil and pain, and it's downright unbearable at times. I hope you have friends and family to help you out.
I'm glad you can find some comfort in knowing we're all going through and feeling many of the same things. I know this board, and especially the people in piecing have helped me through some really dark times...I don't know where I would be without the perspective and support I've gained here. So come back often--we're here for you, and you're always welcome!
