I'm really sorry for your loss. I don't think that people that haven't gone through the experience have any clue of how painful it is. Your mom probably doesn't understand what your going through at all. Talking to others that have gone through it also might help you?
I had a family member that had a miscarriage and we were all sympathetic but didn't really understand the severity of her pain.
A year later I was 2 months pregnant with my son and for an entire day I thought I was having a miscarriage (pain, cramping and bleeding) and my Dr office told me I was having a miscarriage....but after a trip to the emergency room I learned that it was just a bad bladder infection and the baby was fine.
Until that day I had NO CLUE what devastation & sadness a miscarriage brings. I have never cried so hard in my entire life before or since that day.
Needless to say I went back to my family member and let her know how sorry I was that I wasn't more understanding and sympathetic to her loss the year before and she told me that no one was very understanding of her mourning.
I just wanted to let you know that sometimes people "just don't get it" but it doesn't mean that they don't care about your feelings.
