The important point is that you are taking charge of your life. Plus, you have chosen a very confident approach.
Remember this formula -- cleanse[kills] and build up[rebuild]. It will take longer, but you will feel better during the cleansing.
I took charge of my life when I was bed-ridden, but MDs called me dilusional, neurotic, and prescribed psycho meds. Just made me feel worse. Now, I have a life again. Made liars out of a few MDs, too.
