Hysterectomy (children mentioned)

I have been trying to conceive for 8 years and have now been advised to have a hysterectomy as I have cells which could turn cancerous - Hyperplasia. I'm devastated but know it has to be done. I'm hoping I can start to get on with my life and be happy. My head knows what has to be done but my heart hurts like hell. I'm 42 this month with no children and now no hope of any. My hysterectomy is in less than 3 weeks and I just want it over with!!!
