Greylove - I think you need to try and not think of yourself as incompetent. Right now you have done the right thing and handed yourself over i.e. your therapist is helping you with your mental wellbeing, while you pdoc is ensuring the medicine keeps you stable.
You were only recently dx'd - give the medicine an opportunity to work, and unfortunately you need to be patient to work out the correct combo of meds too. You are not an incompetent person - it is a temporary state while you learn to accept and deal with it. There are many people on here that hold down high-profile careers and have families - there is definitely hope.
You've overcome a major hurdle in letting yourself go to therapy and to a pdoc. You have not let pride get in the way and sought help.

Feel free to PM me or post on here - we will support you every step of the way. It'll just be a matter of time and you will be able to take control of your life again!
