Waking up crying

Waking up crying not like just a tear or two but like immense amounts of pain crying. I saw my mom in my dream and she was laying on her bed at the house and I was sitting on the bed cross legs playing with her hair. She looked at me and say "I won't be here long" I responded with "Be here long?" and she said "I wont be here long without you" I told her that Eric says she will always be with me and she said "I will" and I started to tear up and I said "Like right next to me?" and she said "I will" and then of course I started sobbing and woke myself up and was so upset I feel like when I start crying when she talks to me in my dreams I scare her away from wanting to do it again and I had so many more things I wanted to ask her and I fucking ruined it by crying and waking myself up.......
