Sky, go ahead and cry! It's been 6 months since my Mom died and I still do. Sometimes I just go to the grave to have a talk with Mom. Most of the time I end up crying but I feel better afterwards. I know my Dad and my brother are there with her and they'll take over where I left off taking care of her. I do miss her terribly but am glad she didn't suffer long (she was only sick about 4 weeks). Anyway things will get better in time. I found that with my Dad it took a while but I did stop crying and am glad for the time I had with him. I'm sure it will happen with Mom too. Give yourself the time you need. Some days will be good and others you'll miss her A LOT.
Hang in there and take care of yourself!
Be well,
Joe
