I was posting a reply to the above question at another site, and thought that I would add it here.
Philippians 4:6-7 (Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.") has gotten me through two miscarriages, a crazy job and lots of other "stuff", but it wasn't until I adopted my third child (a real doozy) that I went back and read the verses before 6 and 7:
Phil. 4:4-5: "Rejoice in the Lord always. Again I will say, rejoice! Let your gentleness be known to all men. The Lord is at hand."
On those days, when my sweet son would scream at me all day long, I would just sing a little louder "Rejoice in the Lord always and again I say rejoice!". Often, he would stop screaming just to try and figure out what was wrong with mom.
And the reminder to be gentle with this angry child, who was just reacting from his damaged soul, always helped me to get through those long first days and months. I would just imagine Jesus, sitting there in my chair, with his arms open, ready to hold both of us.
God is good!!
