I'm sorry you're hurting, Growli. Try to remember that what you have with her is the best of her: Moms have their own needs, but when she's with you, she's there for you only. I think she said this now so that you'd face this pain before you leave for break. She's taking care of you.

Something else to consider: we all face the pain of realizing that our parents can't meet all our needs--it's just that most of us are so young when it happens that we don't remember.

You haven't lost her as a Mother: you can hold her in your mind and heart as your "Mother archetype." She can be available to you in your mind and heart whenever you need her. This belief can co-exist with the realistic knowledge that she isn't your Mother in the flesh. The intensity and power and comfort of this belief can be life-changing, and it can never be taken away from you. It's far more powerful than any "RL" connection. Let yourself nurture the connection and feel the comfort.
