Sinner

In a really hard time of my life i l doubted in my faith and gave in to sin. I've been trying for a long time now to get right with God but i keep failing. I no longer feel the desire to pray, or read the bible. I want to be the girl that used to sing and dance for the Lord in church from the heart but I feel that I have been so much of a sinner I no longer now how to do that. I feel so far away from God.
