You have a serious illness. Its similar to having cancer or some other life-threatening disease. So, deal with this like a serious illness. You need to find the best medical help you can. You need a doctor that will either find a way to cure your disease or at least reduce its symptoms so that life can be livable.
My advice is to find a good research hospital with psychiatric clinical staff. Go see someone who specializes in bipolar disorder. Dont go anywhere but a research hospital. All doctors are not equal and the best doctors practice at these hospitals. Psychiatrists are medical doctors that know about all of the medications and their side effects. They will try various medicines, adjusting doses, etc until they find something that works. Be patient. Stick with it. Don't give up.
Don't rely only on a psychologist or "therapist". They are not trained in any aspect of medicine. They do not understand the biological basis for your disease or how or why the medications do or don't work. Talk therapy has its place, but you need stronger medicine.
