Need prayer for family's relationship and myself

Please pray for my family's relationship with one another, and a strengthening of my parents marriage. Please, pray that my father over-comes his alcohol addiction and to never be brought up to it again. Also, pray that I may find peace in my life. Problems in my life have cause me to become bitter with everybody. I'm constantly afraid my parents will separate again, and it's caused me to Fall into a mild depression. I feel myself falling away from God, and I'm horrified. I know He says he'll never leave me, but He feels so distant. Thanks for the prayers.
