Dear Heather
SSRI's(Serotonin Specific Reuptake Inhibitors) are medications that are proven to be safe and effective in the treatment of depression, anxiety and several other psychiatric disorders. Nortriptyline is a medication that belongs to the class of tricyclic antidepressants. We can not say definitely that body chemistry will be changed in every person suffering from somatoform disorder. Severe stress can exacerbate the symptoms. SSRI's may help dizziness but some times, exacerbate it. I would recommend that you talk to your doctor about your concerns.
Sincerely
HFHS-M.D.
