Dear Kelly,
Sorry to hear of your state. You ask about Lithium. I am no expert, but I heard that the drug has horrible side effects, especially in long term use on kidneys and I believe also the liver. I too believe that being seen by a homeopath would be the best solution and to do so in the "down" period of depression seems obvious to me. It is important for you to know that you are not "nuts" or anything - your ailment is a form of a diseased state which needs to be addressed. I congratulate you to seek help, that is more than most manage to do. I wish you good luck in finding it.
Best wishes, Claudia
