If you've never fasted while reading his Word, I highly recommend it. Just a light fast; postpone one meal. It creates a powerful bond with the Lord that makes you feel his love and comfort. It's quality time with the Lord. Also say the Lord's prayer over and over again.

What you did was great. You asked for help and told the truth. It is the first step to have a better relationship with God. Maybe you think that you are useless and weak because you are asking God for too much help but no. God is being happier because we are asking him to be in every part of life. God shows his power through your weakness. It is okay to lose. We are saved through God's work not ours.
