My prayers go out to you Balla! Forgiveness can be extremely hard ( I know cause I have alot of unforgiveness towards people in my life). However I always try to remember unforgiveness harms me not the person I have a grudge against... forgiveness can be so liberating and reconciliation can be a direct consequence because of it. So I pray that you can recieve the strenght to forgive and that things can be sorted out between you and your sister.
