This type of thread isn't allowed here -- we cannot tell you what your doctor will prescribe you, nor tell you what to say to your doctor to get any prescriptions. Lexapro is an SSRI and meant to be taken daily, and lorazepam (ativan) is already a benzo, and you already have a prescription for it.
If you mean senior year of HS, that means you're 17-18 yrs old and starting on daily benzos now is really not a good idea, since you won't learn how to deal with your anxiety without drugs and will end up relying on a pill to make you feel better from such a young age.
