Make this quick.
Think of the bed as a place to seek comfort. Means that something happened, and you haven't dealth with it in your heart. I got 4 ideas that could work for you.
1. Pray, just a general conversation with the Lord. It could be about anything, specially what is weighing heavy on your heart.
2. Get a note pad and pen, start writing while your in bed. Write about anything, good bad or the ugly. When you write you let your life shift a little. Allowing the thoughts to let out on paper making it clear in your head. Oh DO NOT THINK ABOUT WHAT TO WRITE, WRITE WHAT YOU HEAR IN YOUR HEAD. Inner voice if you will. (BTW this is another form of prayer

)
3. Focus on the small blessings God has given you. Self pitty can cripple the creative mind. If you learn to view all the small good things going on in your life. Help you break free from it.
4. Find things that intrest you or you like to try. Go to the library or book store to give you small fun activities to do. Keep it simple, nothing fancy.
Prayer and writing in bed are the 2 I want you to walk away with. Trust me, they will help.
