Hello I know what your going through I was diagnosed with a past infection of ebv about a year ago and got sick as a dog off and on so I'm assuming that it's a reactivation. It's been almost 6 moths of this and all I do is want to sleep. My doctor said I shouldn't feel this bad unless it's a weakened immune system. So my advice to you is to rest drink lots of water and take a multivitamin and eat healthy. One other thing to do is make sure to brush your teeth twice a day and gargle warm salt water every 2 to 3 hours. Just listen to your body.
