Lara, you wanted to know what to do:

!. Stay on your mood stabilizer
2. CALL your pdoc and tell him a depression is on the way, what can you do for it.
3. Follow instructions from pdoc.
4. Do not, I repeat, DO NOT stop taking your bipolar drugs. An antidepressant alone will not make you a happy, energetic, la la la manic. I will likely kick you into full blown mania that will land you in the hospital, totally out of control. You DO NOT want this.

That's my opinion anyway.
