^^ Yep, there's a reason you should be careful about getting prescribed benzos, especially if you've had problems with addiction already. In fact, here in Australia it is almost IMPOSSIBLE to get prescribed benzos of any description, ever. I am an alcoholic and I've been trying to get a short prescription of temazepam to help with the insomnia while coming clean off alcohol, and no-one will prescribe it to me. Pretty harsh, but I can understand where they're coming from. Benzos are pretty damn addictive so for anyone who's clearly got addictive tendancies, it is NOT a good idea getting caught up in a benzo addiction.
There are other ways and other medications for coping with anxiety. Your best bet is to speak to a doctor and get a referral to a psychologist/therapist/counsellor. Good luck man.
