Natural healing process- Opinions?

Hi, I had a stroke five years back and has overcome it completely. Still, I face the consequences and am afraid of my health condition. I am not sure whether anxiety and fear are causing this condition, but I need help desperately, or else I will die out of stress.
I am forty-five and I constantly have a heartache. After having an angiogram, it was found that my heart arteries and blood vessels constrict severely and that is causing the pain. So I am on medication. The doctor prescribed me Clopidogrel and Montelukast tablets to ease the pain.
Sometimes, I face the following symptoms:
*dizziness
*headache
*weakness in the muscles
*blurry vision
I don't know exactly what is wrong with me. I am tired of taking medicines. I have been depending upon these medicines for so long. I think they are going to affect me negatively if I continued to use medicines at this rate. I am thinking about having a natural healing process ( http://www.pinewoodhealth.ca/ ) from Toronto as I have heard that they make use of naturopathic medicines. It is said to treat not only the symptoms but also the root cause of the problem. Is there anybody over here who has undergone a similar treatment before? How was your experience? Please share!
