Unless you weigh like 50 pounds, no, you're fine.
I can tell by the fact that you can still type coherently that you're not even on the radar of "overdose" with alprazolam.
Id assume you're quite young and very new to the scene, especially benzo's (forgive me if im wrong), but do some reasearch next time before you decide to take anything, and know what you're getting into.
You're fine, chill out a bit.
