My mother's old manic-depressive behaviors (fear, OCD, financial insecurity, lethargy, depression, mood swings) kicked in about the same age I'm at now. She took Norpramine over the course of several winters to combat what they may have thought was Seasonal Affected Disorder and she didn't have a depression again. I have some truama and PTSD in my background, and have done plenty of therapy -- looking for some answers after a yr on Lexapro at a low dosage that doesn't appear to be working. Please help.
