Its easy for anyone to say to you that you need to just move on but I know that is not easy. My wife had 3 miscarriages before she finally carried to term. This was only achieved because I insisted she move from her own doctor to mine after her doctor advised her to "just keep trying".

My doctor prescribed a course of injections because, in his opinion, my wifes immune system saw the feotus as a foreign body. Anyway, I am sure your sisters understand your distant nature and are feeling really bad themselves and wanting to help. They may even be avoiding the subject for fear of hurting you.

Speak to your doctor and dont accept the brush off. In the meantime, try to enjoy becoming an auntie, shutting yourself away will encourage the "dwelling". As for stones, "Clear Quartz" or "Rose Quartz" are perfect for healing and cleansing and help to focus the mind on more positive outcomes. I would also suggest reading up on something called the "Laws of Attraction" which is basically all to do with positive/negative thinking and what each achieves.

Take care and big hugs.
