As far as the east is from the west, so far hath he removed our transgressions from us.
People may remind you of your past. They will remind you of the wrongs you have done, but God forgives you. He removes those sins to a point that they can never be held against you. Just think about it. You can start walking east, and you will never get to the west. God loves you so much that he forgives you, no matter how bad of a person you have been. So, turn to God and let him cast your sins as far as the east is from the west.
