Can anyone help me and figure out what's going on?

I'm urinating frequently. This morning I went to the bathroom after drinking coffee understandable. I didn't drink after that but shortly after I had to go again. Then again when I barely ate anything. This has been happening for a week now. Along with nausea and stomach pain and back pain. I have been eating larger portions when I never eat this much. I do work out after and try not to eat a lot. Sometimes I starve myself from food because I ate a lot. I am VERY active yet I'm starting to gain weight. I also am very tired lately/fatigue even when I get enough sleep. No I'm not pregnant.my ex and I were sexually active (a month ago we broke up) but I took two tests because I thought I was. Negative twice. We used protection as well.
