Dear New Girl,
What a fascinating account you tell. But I am disturbed by something you wrote: "God showed me my book of life, my whole life flashed before my eyes, the pages were spinning fast. I woke up crying because, it was bad, and I know I haven't done enough on this earth. I think that I have been given reminders that I am not here to have fun, and am not here for my own entertainment. I have a lot of guilt."
God's purposes are not to bring guilt and condemnation to you for your past mistakes. Quite the opposite. Seems to me that you have learned much from your experiences and you are now busy trying to effect positive changes into the lives of others, and that is precisely what it's all about. Guilt is a totally unproductive and harmful emotion when prolongued. It's purpose should be very temporary to bring about positive change, and that it already has achieved, so dump the guilt and shame.
There are a number of other wonderful forums on CureZone that can be of great help to you.
Peace and Love!!
