You are not worthless and you do not deserve to be treated poorly by your parents! I have parents who despise me and treat me inferior to everyone else...even strangers. I just stay away from them as much as possible. I know that is disrespectful in some people's eyes, but for me it is survival. I do know that forgiving others is not for them, but it is for those of us who have been hurt. When we forgive, they have to live with themselves, but we can have peace in spite of how they treat us. We will always have scars, but we no longer have to bleed.
