Hi. I am going through this thing with fibroids, painful especially during my period?

Bleeding, anemic, extra tired, getting frustrated easily even lil depressed at times and lack of concentration because of tiredness. I thought I was ready for this upcoming hysterectomy next month, but now I am having mixed feelings yet knowing I do not want to continue to bleed heavily, extra periods, less drive, large uterus size of a 6-7 pregnant woman!!!! I have not been myself in a long long time. Why do I think these fibroids will shrink and I won't have go through surgery, but they are pretty big and do cause me problems. I had a pap smear done and it came back normal. Will I get my life back after this surgery, will my stomach go down, flatten or something? I really cant continue with this but yet getting nervous and need encouragment from someone who been through this. Please respond to my question.
