I Have A Bipolar Disorder, I Was Diagnosed In 2002

I have a bipolar disorder, I was diagnosed in 2002 after my husband was diagnosed with pancratic cancer. I believe I had it for years but was never diagnosed correctly. My husband lived for five years after he was diagnosed with cancer. I was his full time care provider. I attemped suicide in 2008 due to a prescription overdose. (I took over 150 pills. When I arrived at the hospital in a coma, not breathing and all my organs shutting down, the doctor told my family I was dying and to say good-bye. I did not die, but was in the hospital three months. I am alive and functional due to God's Grace. Because of the above I was prescribed the following Lamictal 200 mg. 2Xdaily, Zoloft 100 1/2 mg. @ bedtime, SeroquelXR 50 mg. 1 @ bedtime, Ativan 1 mg.x3per day, Buspar 10mg x 2 per day. Other meds: Zantac x 1, Protonix 40mg.x1,Sucralfate 1 gm x 4, Ditropan ER 10 mg, Lopressor 50 mg x 2, Nebulizer PRN, Oxygen 2 ltrs HS, . I believe I take too much medicine; can you suggest what I can discuss with my PPC?
