Where do I go from here?

As each day passes I find myself wondering where do I go from here? What do I do?? After two rounds of IVF, two pregnancies, and two miscarriages what do I do? Should I try it again? Is there something seriously wrong with me? Why can't I just be pregnant all ready? I find that I can't get away from it. Not even for a minute. I go to work and put a smile on my face. But inside I am sad, upset and afraid I will never be a mother. I turn on the radio and they are talking about being pregnant. I open a magazine and some new movie star is announcing her pregnancy or showing off their new baby. It reminds me more and more that I am not pregnant and makes me feel like I never will be. I hate this. I just don't know what to do. I don't know if I can handle another round of IVF all the shots, it is physically and mentally exhausting. If I do it again I am terrified of another miscarriage. I just don't know if I can bounce back from another one. It is too painful to go through again. So I am asking where do I go from here????
