Listen to janissa, she gave you very sound advice. Your mother is not worth the anxiety and grief she is causing you. It's time to move on with your life. Forgive her for her weakness, pity her pathetic life, but don't let her destroy yours. You only have one life to live, live it and forget she exsists. If she tries to contact you again don't answer her, just ignore her, she'll get the picture eventually and leave you alone. And you will be much happier with her completely out of your life. This is the voice of experience talking, you owe her nothing, and you need never feel guilty for your discision.
