support please

so I miscarried in december last year, this month was when my baby should have been born, I'm struggling to cope mentally and physically, my partner and family are no help, I'm getting sick of being told "it's in the past", "just move on" and being told I could always try again, but this baby ment the world to me, I just don't know how to cope, no one could give me an answer of why, when I went to the doctors I was told to just forget it and move on. Why can't no one understand that I can't just move on like my child ment nothing, I'm so lost and confused, my partner acts like he doesn't care, my own parents didn't want to talk to me about it. I'm completely on my own, I just don't know what to do anymore. does anyone have any coping strategies because I'm falling apart and I feel helpless.
