So I know I have anxiety...but anxious people get sick too. How do I tell if my symptoms are real or not? Going through a period of great struggle at the moment. I constantly fear cancer and am currently experiencing fatigue, dizziness, and ear blockage. Scared to death of a brain tumor or leukemia. Those are the two worst things I cAn think of. I'm so miserable all the time and can't enjoy anything. Just restarted Zoloft asthat has helped before (but was feeling dizzy before that so can't blame the med). My usual tricks aren't working to feel "normal". I'm scared of the dizziness, scared of the fatigue, and I'm so sad.
