I think you should write her a letter. And wait a day after you write it before you decide to give it to her. But don't change it after you write it. But tell her all you feel, tell her how angry you are and how sad and how hurt. Get it all in there

I suggest writing something at the end before you begin. Something telling her that you're trying to let her know your feelings in a way that is more helpful and less confrontational (an angry confrontation would be really bed) than a shouting argument. You're just trying to get it out there without yelling or anything. Do this all so that when she/if she reads it she knows you're not going to storm over in an angry rage or whatever You know?

Make sure you mention what you dont' understand about what happened and all that. Have some of it be clear and concise and then let your emotions run after. At the least this will be therapeutic to you and give you a good outlet to get your feelings out whether you give it to her or not.

But keep on a chugging no matter what. Lifes a bitch and its gonna throw tough shit at you. I have a feeling you're a strong, tough guy so that means life is gonna throw stronger tougher stuff at you than many people get.

Just keep a goal in mind always. Living life to your best and making a good life for your daughter. That's all you can do right now. Life is long, you don't win it in a sprint. Take things slow and try to relax (though I'm sure that's the toughest thing).
