Well, to me, it does sound like you have plenty of anxiety. However, I think that's just the tip of the iceberg. Is it possible you could have post-traumatic stress syndrome after the recent miscarriage? Or have you ever been evaluated for depression or another mental illness? I know it's hard not to focus on the physical symptoms when they seem to be taking over your life, but I think a trip to a psychiatrist right now would probably benefit you more than a primary care physician. Take care of yourself, and have it looked into. We're here for you!
