The first thing to do is to love yourself by doing things that do not complicate your life.
Second, love God and associate with people who love God. Make friends among God's people.
God is love and people who seek him find love and peace of mind irrespective of their previous experiences.
I have heard a whole lot about Jehovah's Witnesses and the love among. And they preach a message that has transformed the life of millions the world over.
Hardened criminals have become people peace-loving people when they took time to study the bible with Jehovah's Witnesses.
Find a Jehovah's Winess in your area, attend their Christian meetings, and start a bible study with them.
You will experience a change. Your life will be transformed.
