Well you don't have to be sorry. This place is the grea-*test*-('") for this kind of thing.
We can all say things like this and instead of feeling silly and foolish, we can just feel supported and sustained by the other members of the forum. Many of whom will have felt something approaching exactly the same way at sometime in their lives.
We understand, because we appreciate where you are coming from, and we want to help.

If she's your mum then she probaly worries about you anyway, but if you don't talk to her and let her help then she will worry herself to death without ever knowing if she could have helped you put a stop to all this.
Mums worry, it's just what they do!
You can't avoid that. But even if all she can do to help is cuddle you, ask yourself would you rather deal with this with cuddles or without?

Hope you manage to talk to her soon, for both of your sakes.

Look after yourself girl.
Darke.
