I'm in the minority here, but I've never subscribed to "God helps those who help themselves". That phrase cannot be found anywhere in the Bible (and I think it's pretty much the definitive resource ;). What CAN be found in the Bible is this:
Give all your worries and cares to God, for he cares about you. -1 Peter 5:7
Give your burdens to the Lord, and he will take care of you. He will not permit the godly to slip and fall. -Psalm 55:22
Don’t worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. -Philippians 4:6
For God has not given us a spirit of fear and timidity, but of power, love, and self-discipline. -2 Timothy 1:7
Don’t be afraid, for I am with you. Don’t be discouraged, for I am your God. I will strengthen you and help you. I will hold you up with my victorious right hand. -Isaiah 41:10
“So don’t worry about tomorrow, for tomorrow will bring its own worries. Today’s trouble is enough for today." -Matthew 6:34
“That is why I tell you not to worry about everyday life—whether you have enough food and drink, or enough clothes to wear. Isn’t life more than food, and your body more than clothing?" -Matthew 6:25
"I, yes I, am the one who comforts you. So why are you afraid of mere humans, who wither like the grass and disappear?" -Isaiah 51:12
And the very hairs on your head are all numbered. So don’t be afraid; you are more valuable to God than a whole flock of sparrows. -Luke 12:7
So if you sinful people know how to give good gifts to your children, how much more will your heavenly Father give good gifts to those who ask him. -Matthew 7:11
“So don’t worry about these things, saying, ‘What will we eat? What will we drink? What will we wear?’ These things dominate the thoughts of unbelievers, but your heavenly Father already knows all your needs." -Matthew 6:31-32
And there are hundreds of verses like that in the holy book. When I need to give it all to God, I spend a little extra time every day reading my Bible (I read it every day, but sometimes I need to read more! :). Spending some time with God in his Word is one of the most surefire ways I know to calm myself down!
I also, like Mary L, "dump" on God a lot! My favorite times to pray are: in the shower, when I'm doing dishes, laundry (we hang our laundry outside and I LOVE to pray for each person as I hang their laundry up! You can do the same thing when folding laundry :), or cleaning, and when I'm outside watching the kids.
If you come to the Lord in prayer, and tell him all your worries, then he can give you peace of mind. Remember that King David himself, who was "a man after God's heart", often complained to God! Job was ANGRY at God! Both these men were called righteous; because they TRUSTED in God. You can scream and cry to God, he can take it. :) All you have to do is remember that it is HE who is in control!
Giving it all up to God is a simple matter in word, but quite difficult to do the first few times in practice. After a while it becomes first nature. :) First, pray to God and tell him all your worries and cares and fears. Then tell him "Lord, I know all things are in your hands, and that I cannot do anything without you. Please give me the FAITH and STRENGTH to carry out YOUR WILL!".
Then, every time you find yourself worrying, stop, take a deep breath, and pray. It doesn't have to be a long prayer, but just a simple "help me remember it's in your hands" will help calm your worried soul.
Giving it to God doesn't mean you stop doing what you can do to help your husband or your family. It's knowing that YOU have NO control and that YOU cannot prosper outside of God's will! When you do what the Lord asks of you, then you are acting according to his will and will be rewarded. BUT remember; the reward is not always for this life or on this Earth!
Also, give a listen to "Starry Night" by Chris August. It's an amazing song!
Hang in there, mama. We'll be praying for you. Feel free to PM me if you want to talk, even just to vent. :)
