When I went through a rough patch years ago I went to my family doctor and he prescribed Prozac for me. It helped stop the depressive state I was in. I only took it six months. I decided I was not going to let my son's life choices ruin my life. I just needed to break the cycle of depression I was in--and not allow myself to fall back in it again. So far so good. It has been 12 years since I stopped taking the anti-depressant.
My doctor also recommended therapy to help me learn healthy coping mechanisms.
