What is your dx? Depression (of some type) or Bi-polar? I've never heard of ppl taking mood stabilizers unless they're bp. From my own personal experience, the mood stabilizers when taken alone (meaning not comibined w/any anti-depressants) made my depression worse. However it is also a well known fact that AD's increase mania or h-mania when used (by themselves) for treatment of bp or mood disorders.
So I think for me if I ever were to go back on meds, I would have to have a combination.
All meds are different. Do you have a pdoc? Definitely talk to him/her. I wonder what your mood swings are like? Is your pdoc aware? I was initially dx w/depression for years, but was really bp maybe all along, but definitely for the last few years.
It is extremely common for depression dx to come first and then eventually bp dx comes along.
Talk to your pdoc/doc, my thougts are with you. Moods swing/disorders are very tough.
Take care P.S. Awesome that you're doing the CBT!
