Help finding questions to ask physicians about my symptoms.

I have had a crazy amount of diverse symptoms since I was a little girl. I have yet receive a for sure diagnosis. Athough I have mostly adjusted to my symptoms over the years so I can tolerate them, over the last few months my health has deteriorated even more. I have chronic pain in joints, headaches, seizures but not epilepsy, fatigue, sensitivity to light and temperature changes ( heat is the worst), upper abdominal pain with symmetrical point tenderness (marble sized lumps), nausea, feeling full after eating small amounts, loss of appetite, unexplained weight loss, hair loss. Physicians I have seen won't look at my symptoms as a whole although I feel they are all connected somehow.
