Sorry to hear of your recent diagnosis. I can relate to the difficulties you face with BP2, and it is true, its not something you would choose to have if given the choice.
For whatever reason, you have BP2. At least now you have a diagnosis, and can start getting the correct treatment. Some people are able to go on and lead 'normal' productive lives while being medicated, for others it requires adjustments in there expectations in life. Whatever bracket you fall into, the future is yours for the taking. You have BP2, it is something you suffer from, but it does not define you, nor should it. Yes the meds and the Pdoc and the Therapy is tedious at best, but if you have those things in place along with medication you have half the battle won - becuase you know what you are fighting.
Never give up.
