Hello my age is 45, 5'3 and 108....starting in March of this year, I went to hospital in the middle of the night thinking I was having a heart attack, they diagnosed me panic attacks and GAD, was admitted and had nuclear stress test to rule out heart problems, all was normal... after several doctors later and a month or so, I am currently taking Lexapro and Xanax XR .5mg after trying 3 other SSRI's...since March I have lost 8 or so pounds, increased bowel movements, heart palpitations, nervous, etc... I have researched over and over and I think I have hyperthyroidism..my PCP drew TSH and FSH which they said fell within normal range...was wondering what other in depth tests can be done? It is driving me crazy and I never feel good
