Ah, man, life has certainly thrown itself at you, huh! Sorry for all that crazy mad HURT you've gone through. You are soooo right though -

No one but YOU can take away the freedom you have in your mind

We can be so enslaved by what has happened to us we forget to LIVE, and forget the past is all just in our mind and no longer exists. It's hard work to live in the now, having learnt from our mistakes, bad choices, or just the stuff that's thrown at us, but it's work with doing. May the rest of your live be free from heart attack and suffering! Boo to prisons!
