Past 3 months i've had rapidly increasin fatigue, night sweats/ chills, pains in my stomach/jointa, unexplained bruising-sores, dizziness, nausea what?

No short answer: If it has been going on for three months and is rapidly getting worse, you must go to a doctor or emergency room, please.

Vague but important: The symptoms could be due to anything from anxiety and depression to lymphoma/ leukemia, peptic ulcer disease or inflammatory bowel disease just to name a few. Go see your doctor and get a physical exam, a good history and some basic lab results.
