Ask your doctor to check your thyroid. And good luck.
Get checked for intestinal parasites, specifically B.hominis. Good luck!
Hey there~
I was reading your question and your symptoms sound very familiar. What you're describing sounds a lot like a panic or anxiety attack. Did your doctor happen to mention that you that you may happen to have an anxiety problem/disorder? I'm not criticizing, and in fact I've suffered from panic attacks since I was about 14.
I do hope you get to feeling better!
