Thank you all!
BK and Cloudy: Thank you so much for your concern....Still, I'm not a total invalid

OK as a matter of fact I am some of the time, but I simply refuse to let it control my entire life! I promise that I will rest when I feel I need it, but what's the purpose of my life if I cannot do anything anymore?! The afternoon after I got my blood test, my boyfriend took me shopping (he's not too keen on spending the entire day going in and out of clothes' stores, esp. because he's so busy

) and even though I collapsed for a day afterwards, I was glad that I did it. I try to have as much of a social life as I can, because I fear that sitting at home doing nothing will make me feel even worse.
As for the update on my "status":
My GPs first guess was M.E. (i.e. chronic fatigue syndrome) but he isn't sure. He having me tested for about a zillion things (liver, kidneys, diabetes, even rheumatism) and I have another appointment in about two weeks. Then, he will check everything the bloodtest didn't cover (heart, lungs etc.) and he'll also tell me the result of the test.... so keep all your fingers and toes crossed you guys!
