Unquenchable thirst when drinking, extreme fatigue?

It is apparent you are trying very hard to self diagnose to avoid going to the Dr because you fear he will dismiss your complaints as hypercondriac and you will feel foolish. I have been there before. I also suffer from panic and anxiety disorders. But I have got to tell you what your doing is the wrong way to go about things. You have symptoms that concern you. Go see your Dr and let him who is trained and educated and qualified help you. Not a bunch of people you know nothig about and who likely know nothing about medicine. Go see your Doc, OK?
