I know from experience that medication will not eliminate all symptoms. You also have to learn coping skills to handle your symptoms when they arise. When you find the right med combo it can definitely help but it won't take it all away. And sometimes it can take a very long time to find the right med combo. I suggest being assertive with your doctor and telling him/her that this isn't working for you and you want to try something else.

Work can also contribute to depression, especially if you're unhappy there. I don't know if changing jobs/careers would be beneficial for you but it might be. I know my job definitely contributed to my instability and that since I've started my new job in September it's been much better. I also know that I may not be able to make a long term career out of teaching if bipolar worsens in severity. I'm doing well now but I know I couldn't slog through a severe depression at this job. And eventually I may not be able to handle to stress anymore. I hope not and I hope that doesn't happen anytime soon but it might.

I hope you're able to find some peace in your life, whatever you choose to do.
