Depression

I have a 4-year-old and a 4-month-old daughter and my husband does not know the Lord and is gone all the time and I just feel so alone. I know that the Lord is with me and that my relationship with Him is what is going to carry me through, but still I find myself slipping into depression. Please pray for my husband's salvation and for me to strengthen my relationship with the Lord and find a renewed sense of hope.
