DorothyP, I'm so sorry to hear of your loss. I lost my mom when I was 18, well before becoming pregnant so I haven't got the exact same experience. I agree with what has been said above about councelling, I had some when I was pregnant as I found it very hard, lost of mixed-up feeling and was very afraid of not bonding with my baby. Bonkerz story is a tough one too. If your midwife doesn't seem keen to refer you talk to your GP. In fact, most hospitals have a "women" oriented counsillor attached to their maternity units so you might have easier access to a councillor than you might think. Personally I don't know where I would be without that help which I got throughout my pregnancy. It was really good to talk to someone who could listen to my grief and talk me through my feelings. Based on Bonkerz story I might count myself even luckier to perhaps have escaped PND. My councillor was based at the hospital I was booked in too (St Georges in London). Where are you booked in?
I know what you mean also about wanting to share with your mom all that's happening to you, and also the shopping bit. I kept wanting to ask her about the things I was experiencing, if she had experienced it too. It seems like pregnancy is a great bonding experience for mothers and daughters and I feel I missed out on something important. I still find it hard to see other young mothers with their children and their own mothers walking in the park, playing, eating out that sort of thing. I look forward to doing that with my daughter and her children though. It sounds like you have family who you can talk to about your mother and who can tell you stories about her. That is so important (if not quite the same as the real thing). If you have an aunt that you are okay close too let her give you advise too, it will be nice to have some older female attention after the birth of your baby too.
When I was pregnant I posted a similar message to yours and I got some advise from another bereaved mothers, one of which was to start a 'memory book' (scrap book/journal) which you can share with your child when he or she is older. Making it will be good for you and let you grief now, if your ready that is, but will also give you something to show to your child and talk to him or her about their grandmother too. I am doing this myself and plan to have many afternoons with my daughter looking through it.
DorothyP, I feel for you and will be thinking of you.
