Heroin will destroy your life and turn you into someone who is not even you. I have seen it happen to too many people. I randomly caught "Oprah's Lifeclass" on tv last night and found it really helpful in terms of facing fears and changing the story that we tell OURSELVES to be true, but is not. There is actually a side story about an addict in the beginning. You can watch it for free online if you want. I hope you can find the help that you need.
