You can move on!!!

It's not always about forgiveness you know. You accept that your alcoholic friend did not mean to hurt you but, you WERE hurt and felt enormously let down. You say you want to forgive her but not able to. You have lost trust in this person and when you've lost trust it is very hard to regain it but, be gentle with yourself and give it time and you will slowly work through your feelings.

Meanwhile take it easy and let go. Life has a way of sorting things out for us... have faith.

By going along with feelings....
You unify your emotional, mental and bodily, states

When you try to fight or deny them...
You divorce yourself from the reality of your being
