SMU,Your choice seems to be - give the medication a try - a fair try - and hopefully it will help you or choose not to take the medication knowing that your health anxiety is out of control.
I do take this med and it has pulled me from some very dark holes. I know taking a chance scares you but sometimes it is the right thing to do as long as you keep an open mind and know that it may take 6-8 weeks to reach a therapeutic dose.
I wish you peace,
