i'M sorry for what you are going trough. Have you talked with your therapist about this? I can only say if your having this much anxiety over going to texas, then do what rights for you and not go. If someone put someting in your drink to make you feel drugged, If I were you I would not go. Send a birthday card or make a phone call. Just explain to your mother that this just is not a good time for you to go to texas, but wish her a happy bithday. Do you have any coping skills to reduce your anxiety?
