You sound like you get a high from it. "It's gone in 30 minutes." Mix the Xanax with sugar pills and trust me, you won't know the difference and like a miracle, it will be gone in 30 minutes even with the sugar pills. It's all in your mind. Find other non drug related coping mechanisms for your anxiety. Find the root of your problem versus suppressing the symptoms with a drug.
1. You don't "get high" from Xanax. You are showing your ignorance.
2. If you had chronic panic attacks (or even 1 true panic attack-not just generalized anxiety) you wouldn't be such an ass about this.
OP, you aren't going to become dependent from short term use of Xanax. However, there are better drugs, like Clonazapaem, that your doctor can prescribe for anxiety that can be used safely for a longer period of time. Are you getting your meds from an internist or a psychiatrist. I would recommend getting your antidepressants and anxi-meds from a psychiatrist. They are better trained to prescribe this drugs and get the right combination safely. This is not one size fits all medication
