Can i still be a therapist?

My dream is to be a therapist as my career. But im like 98% positive i have Bipolar II (Bipolar Disorder where the "high" or Maniac periods don't reach their full extent) so my question is, would it be a bad career choice for me? All i want to do is help people who go through the kind of pain i go through and if my mental state is going to affect how i can help them in a negative way then i feel i need to find a new dream job...
