Been under a tremendous amount of stress for a long period of time now. Dx'd with major depression and generalized anxiety disorder. 48 y/o (perimenopausal) female, otherwise in good health experiencing dizziness, lightheaded, eyes out of focus, eyes light sensitive, easily upset, dwell on things, palipitations, elevated blood pressure, tightness in chest, body aches, feeling of doom and anxious. Dr. prescribed a low dose of Zoloft and xanax. I'm afraid to start taking them fearing the side effects will be worse than the anxiety symptoms. Please help. Is it common to feel like this? How can I calm down?
