Sick for 6 years.....can someone help me figure out why?

I have a similar sort of problem but not to the extreme that you have, I am just tired all the time and nauseous. I had glandular fever 18months ago when I was 15, and ever since then I haven't felt right. I used to go out with my friends all the time and now I just never have the energy to and drinking causes my symptoms to worsen so I just avoid that. My immune system is also rubbish, I always have something else wrong with me e.g - throat infection etc. After being back at the doctors so many times he finally suggested that I probably have ME (Myalgic Encephalomyelitis) which is basically the same as CFS (Chronic fatigue syndrome). Unfortunately there is no cure, it can go in a few months or it cannot go at all.
