Feeling Bad

I went to the doctor yesterday and was given to opions continue on depo or have a partial hysterctomy. When I brought it up to my husband he got cold and made the comment he thought I was going to try everything. I have been living in pain for 2 years all I asked was to live pain free for at least a year before we tried and I haven't had 2 weeks of no pain. I am tired and frustrated and feel that since I'm not diagnosed with cancer everyone thinks it is just in my head. I am 30 years old and have had female problems since I started my period years ago. Not only the endo but have ovarian cyst it seems like all the time and they burst and sometimes I'm in so much pain I want to go to the ER but know they can't do anything for me. How much do people expect me to live in pain and frustration? We have been told the chances of me caring a baby full term is 20% that is a very small percentage. I know emotionally I can't handle that and my body is telling me enough is enough. How do I make other people understand what I'm going through when doctors don't even have a 100% guarantee they know what they are talking about half of the time. I have seen numerous doctors and the one I am seeing now is suppose to be the best in Dallas..... so what do you do when he gives you these two options? I'm so tired of living in pain and so tired of endo.
