Do you feell guilty about something bad you did ? Get on your knees and pray and repent ask god the creator for forgiveness .
God knows we are not perfect , god never created us to be perfect . That is why jesus died for our sins. Our creator wants us to love respect and help one another , we are all brothers and sisters.
God is the only person that can judge you for your past , the only thing you can do is be a better person than you were yesterday . If you fail try over and over again. GOD LOVES YOU
