My first child was stillborn give years ago and while I feel fine most of the time and have another child now sometimes seeing something about babies will trigger me and I can feel like it's just happened.
Last night I was watching a film and scenes of the main character holding her newborn in hospital sent me right back there. I cried so hard I had to get up and go to the bathroom so as not to wake my DH. I felt like I was reliving it and remembering holding her, having to leave hospital without her, making the decision to have a post mortem done, the funeral, being on mat leave and that horrible alien feeling of being a mum without a baby and either making people feel uncomfortable if they asked if I had children or feeling guilt for pretending she didn't exist even if momentarily.
