One reason it helps me is because talking about it helps organize all the jumbled thoughts in my brain. I worry a lot (I'll talk more about that next week), and when I have all these thoughts of "What if?", it makes me depressed and crabby. I treat my brothers badly, I talk back to my parents, and I don't have a good attitude about anything. I hated being that way, but I never really knew how to deal with it. Well, being able to confide in others has really helped me in that area.
James 5:16 says "Confess your faults to one another, and pray for one another, that you may be healed." I read that in my devotional literally the same night after talking to my friends and I knew that I had done the right thing. When you are feeling like the devil is pounding lies into your head, talk to someone about it! As my devotional says, often just saying it to someone can get rid of the problem. As long as you keep these things in your head, they can continue to hold your hostage. So go and talk to someone you trust and let them help you and pray for you. I can tell you right now, it will make a difference.
