What Causes Stiffness In Neck Along With Pain In Joints?

I m only 20 this year. My illness is quite complicated. I used to eat a lot of junk, oily and unhealthy food since young. But i exercise intensely and regularly too. I wasnt ill then. Ever since last year june i broke my left shoulder and stop all my intense exercises abrubtly like dragonboating. I have been feeling depressed and my appetite grew. I drank alcohol, eat a lot and slept very late at night. I developed all kinds of symptoms overnight in about 3 months. Eyes become weaker, i cant sweat much, very hard to wake in the morning, foggy headed, stiff neck and other joints and other smaller ones. Do you think these are related to my liver? Is it possible that all these symptoms erupt overnight? I have done 2 liver flushes recently. Released lots of black sticky stinky slimy stuff which they call it liver sludge. No stones yet. But my symptoms still aint getting better though.
