too much bleeding

Hello. Im 36, 2 children, tubes have been tied for 9 years now. My periods are out of control. Ruining everything I put on, including sheets, towels and matresses.My family is ready for a divorce because of my moods. Some moods are legitimate PMS others come from worrying about if Im leaking or gonna go somewhere and bleed all over the seat in the car! I dont just bleed for a week anymore. Never know when its gonna happen. Have had ultra sound with nothing looking out of the ordinary. My DR. wrote me a perscription for Prozac that I had the option of taking 14 days a month for PMS or just take one everyday. I believe that I can manage the PMS but what about the abnormal and increasing blood flow? I think that I just want to get a hysterectomy at this point. Not take Prozac!!! Any advice how?
