I am sick all the time to and sick and tired of being sick, i have epstein barr ,sounds like you might to start with blood work and find a good doctor who specializes in it.you should get on some kind of vitamin and herb system . dont give into it thats the worst you will get depressed , keep your self busy and push your self and think positive ! a good herb i found is Astragalus root , Pau D'arco , drink lots of green tea , take garlic, viamin c , give it a couple of months but you will see a difference . and oh i feel better if i work out . Good luck!
