Your presence is all that's needed to begin to forgive. It's more than acceptance thought. Understanding why you did and realizing you must embrace your current self take time. Accept your punishment if you hurt somebody and realize what you are now and whatever reasons you had in the past that actually happened. Forgive yourself. Bring peace to yourself and utilize times you have left. Forgiveness can be enhanced by facing what you did and leaving fate to the punishment that awaits you.
