It's up to you -- you can choose to either sow the seeds of discord or the beginnings of a fruitful and peaceful time for you and your loved ones. Remember, forgiving someone doesn't mean that you condoned what they did. It just means that you refuse to let it have any power over you or what you do. Inform your actions with the knowledge and wisdom of your heart rather than letting your ego run the show.
I think forgiving myself might be a good place to start (as impossible a task as it seems right this moment)...
