Hi Steph, I am so very, very sorry to hear about your little girl. How incredibly sad. You have my every sympathy. The early days, just trying to keep going, are absolutely appalling. I remember them all too well (we lost our newborn baby girl nearly five years ago), and I can only say - as you will doubtless have read and heard elsewhere - that the unbearable pain and blackness does, very very slowly, get better with time.
I apologise that I only have a couple of minutes to write this, but I didn't want to read and run. In our area, yes, that was the format of the Sands meetings - sitting together and sharing stories one by one, then general conversation. It is hard listening to other people's stories, but comforting to be in a place where everyone knows how are you feeling. I think that most of them are run in a similar way, though you'd need to check with the local organisers to be entirely certain - maybe an email or text, if you don't feel up to calling? I am 100% sure, though, that if you want to go, but don't feel able to talk, no one will press you to do so and you will be able just to listen. The nature of these groups are such that everyone understands... But if it seems as if it would be too much, then do just plan to go to the next one and then re-evaluate how you feel nearer the time; don't put yourself under too much pressure. Your days are hard enough at the moment without pushing yourself too far beyond your current comfort zone.
Also, just an idea, if you can't go, you could ask the organisers if you could be put in touch with some others, individually, who might want to meet up? The local friends I made through Sands were a lifeline to me in the year following DD's death.
Sending love to you and to your daughter x
