death of a friend

A freind of mine who is the same age as me passed away yesterday from liver desiese. He was a heavy beer drinker, which I am not, but all the same it really hit home with me about getting my body healthy. I have a fatty liver, gallstones, high blood pressure, I am sure high cholesterol and since I had gestational diabites, I'm on my way to that as well because of my weight and eating habits. I've been goofing around with this gallstone pain for a year now. I have done one flush that didnt do anything. I am so serious now about this I need the knowledge you all have. I scared, I'm tired of being sick and am definatly not ready to die. The trouble is the more I read, the more confused I become. So many angles to approach. I want to go the holistic route rather than the dr.s approach. I will be forty next year and my motto is fabulous at forty. But, where do I start. should I concentrate on flushing first, or diet or supplements, all of the above. What is the best diet and supplements to take? should I start juicing? I know everybody has got there own thing, I guess thats why Im so confused and rambling. I'm just scared! I want to start....but where?
