It sounds like you are having normal stress related anxiety, have you ever tried talk therapy?
It is non addictive, no side effects & can help you long & short term.
The short term side effects of SSRI's are not limited to stomach pains or even "brain zaps"
They include, akathisia, suicidal thoughts, even death, so I would see a therapist, as a gyno has no business playing psychiatrist.
Dr.'s admit that they don't know the long term effects of taking these strong meds, I'm sure we'll find out in the near future w/ the number people taking them.
The FDA has issued "black box warnings" on SSRI's, they do NOT use that warning casually!
