It sounds like the meds you are taking right now aren't effective. How often do you see your pdoc? How long has it been since you tried a new med? After I was diagnosed with bipolar it took nearly seven years to find a combination of meds that worked for me. I am fifty-five years old too and there is hope. I seldom have mood swings anymore unless I run out of meds because I didn't drive into town soon enough or something triggers me.

Hang in there. There is hope.
