Can't be happy without crashing

So, no one seems to have the same problem as me, but I have this thing where after I'm happy I'll have a major emotional crash and will get extremely depressed for days, then happy again from a few hours to a week, and then crash, and then go back up again.. I know it sounds like bipolar, but I'm on medication for bipolar and go to therapy and nothing has helped. I'm currently on Abilify, the "miracle medicine", after trying out 7ish medications already, I've lost count. Have any of you had the same problem? What helped? Thank you for any advice/experiences!
