I'm glad you'll have a nice big shoulder to cry on when you go. You poor dear. My heart goes out to you...I lost my Dad when I was 13, and my Mom had a close call with cancer 8 years ago. I appreciate our relationship so much, but she's as human as me and we can still make each other nuts. That's part of the beauty of it.
I know you miss her, your memories will keep her alive.
Do you still dream of her and feel like you've really seen her? I did that with my Dad for years and it was such a comfort.
Hang in there, girl. Take a hot bath, remember her and have a good cry...repeat as necessary.
