Hi LegoPup,
Most likely you and your siblings are still angery at her. When a person's soul passes to the other side all the physical things are left behind, this includes fear, anger all the negative emotions. If she can commuicate with her two sisters, she can definatly try to communicate with you.
Sometimes the hardest thing to understand (this is my belief only) is that your life is planned (at least the major events are) before your born. You plan your own life. Karma also plays a role in it. "What goes around comes around". Karmaic debts must be paid. If in your last life you treated your mother poorly or did something that needed to be evened out in the next life (this one) that may be the reason for the choices she made. She may be a very young soul, just starting out, making more mistakes than learning life lessons and experiences.
My advice is for you to find it in your heart to forgive her and yourself if need be. Then take the time to heal and then try to commuicate with her. Soul to Soul. Not mad as hell child to a bad mother.
I hope this helps you instead of confuses you. I'd be happy to explain futher if your intersted.
Right now just know the universe is big enough for the both of you and the LOVE conquers all.
