I have been with my gf for about 2 years. She told me since the beginning that she has been on abilify and lithium. I don't know the dosages but she's been acting different lately. She broke down crying a couple of times and she just hasn't been her self. This is the first time it's happening. Any advice? She keeps telling herself to be happy out loud and she's had trouble sleeping. I think she's experiencing dark thoughts or bad feelings. Looking for help!
