what should I do?

so today I got a call from the hospital regarding my baby I lost in June. I opted for her to be cremated in mind thinking I would get her ashes back so today I get a call saying they had received a letter saying there was no ashes returned as she was too small and there wasn't enough bone devopled obvious I feel devestated and empty but now what? how can I move on from this? I lost her and now she's gone forever? I can't think of anything to do to remember her by I feel so broken.
