I feel the same way. It's been over a year now of TTC and I've cried almost every night for the past week over it all. I am so frustrated, drained, depressed. I worry I will never have children. Words just can't express how much pain I'm in. I'm sick of the embarrassing, invasive, painful tests. I'm sick of BFN after BFN. I'm sick of going into what will be the nursery and wondering if it will always be empty.
