Do a web engine search for "liver damage symptoms." Those typically include a bloated abdomen; yellowish tint to skin and whites of the eyes; dark urine and light stools; exhaustion, itching, etc.
If you've been using needles, Hep C is a possibility, too.
Go see your doctor. A liver function panel is not very expensive and will help to establish if you have a problem or not. You might be anemic. But you won't know if you don't go . . .
Good luck.
