This made me tear up.... I've been down the infertility path and to not even be able to hear a pregnancy announcement of a friend without breaking down and a baby shower invitation could send me to pieces..

I see you are in UK so not sure if it's the same but in US at fertility clinics they sometimes have therapists who specialize in infertility.... My ob/gyn even gave me a card of a t. That specialized in it..

Perhaps for this issue you need someone more attuned to your situation.
