Tested negative for covid, had my flu shot.

Been losing weight despite binging (though I have been purging after, but usually when I'm in a bulimic relapse I stay steady or gain a little weight), but yeah I lost 9 pounds, stomach hurts, achy, nauseous, tired (and can't sleep, but I attribute this to being towards the end of withdrawal), my poop is kinda light colored, no matter how much water I drink my urine looks like I'm dehydrated, and chills.

Ideas? I don't want to see a doc unless it won't go away on its own.
