I was just going to say that, the Dep thread comm. is not equipped to handle this. You may have to wrong combinations. Are you seeing a shrink or just a family doctor. That makes a huge difference. I think you are on the wrong combination, Abilify and many other drugs risk weight gain, BUT you have the ability to watch what you eat and take control of that. I'm on Seroquel for the anxiety, Depakote sorta for both MS -including hypomania and Lamctil for Depression, it's a good combo. I haven't gained any weight, since going off LIthium. At first I was hungry all the time, but one day I just stopped, I have no idea why, but I'm not complaining.
You should really check out the BP community,there a lot of folks there with copious amounts of knowledge.
You know you might get an answer on the bipolar forum. They have good experience there.
Do you think you might be on too much medication?
Having no motivation or likes is a symptom of depression as well.
