A book I was reading on pregnancy loss tried to differentiate between a focus and an obsession. In my opinion, trying to have a child the "natural" way is like trying to juggle a busy schedule. Trying to become a parent through fertility treatments or adoption or third party reproduction feels like you're spinning plates. Not only do you have to keep track of your cycle or what you must do at each step, but (at least in our experience) our RE was depending on us to help him analyze our cycle and look for clues that were pointing towards a reason for a cycle's failure. It meant a keen focus on my body--how I felt, what was happening, what I did during the course of the treatment. Therefore, it was impossible to not think about infertility. Ignoring it was like trying to ignore a big white uterus in the room.
At what point does the focus to have a child become an obsession to have a child? Are they one and the same and using two different words just puts a positive or negative twist to the same idea? Or is a focus something entirely different than an obsession?
