Hi Axelle and welcome. I have a wonderful daughter who struggles with BiPolar illness so I have some knowledge of it. We have a Bipolar forum here...
http://neurotalk.psychcentral.com/forum38.html
and you will find others there who are knowledgable regarding the various meds for it. I hear your depression talking...
Please know that you aren't alone and talking about what we are feeling helps us. Depression is a beast.
