Im not receiving therapy for bipolar treatment. should i be? or only meds required?

Yes, therapy too: Medications are necessary in bipolar disorder. In most situations these days though, your visits with the psychiatrist are very brief and spread out ("med check" visits). These can be supportive, but do not leave time for working on life difficulties that can arise with bipolar disorder. Working with a therapist will help you develop your life skills and self-care, among other necessary things.

Bipolar: Success rates are higher when medications are combined with psychotherapy, both individual as wewll as group therapy.

It depends: If you are stable, have been in therapy and are not stressed and you know your triggers for your illness well enough to seek immediate help upon relapse, have a stable psychosocial system and hopefully are gainfully employed, then you probably don't need therapy. Otherwise you may find therapy to be helpful with dealing with stress, relationships, and in helping you to prevent relapse. It can greatly improve the quality of a person's life and relationships.
