Do not worry and do not fear - this is what God tells us. Worry and fear have no place in our lives. God is with you. Whatever you have done is forgiven when asked of God so don't carry that guilt. God is not punishing you. He loves you and will never give you more than you can bear. Romans 8:28 is your scripture for a time.

Know that when Satan is coming at you hard that you must be doing something right. Stand and when you have done all you can, keep standing. Resist the devil and he will flee from you. You are much stronger than the devil because you are in Christ Jesus.

Nothing is too hard for God. One thing I know is as hard as we try, we cannot fix ourselves- only God can. So, be obedient to His Words and watch Him work.
