If you don't believe , try asking God for help, anyway. This can help focus you on positive belief in change. And feel free to tell Him about your doubts and frustrations. God can do anything, the Bible assures us, but you have to ask - and be open to Him and his solutions for you. Ask God for the wisdom to know what's right to do - and the ability and opportunity to succeed.
Meditation can be a source of relaxation.

Reading this letter shows you want to change.
