am I over reacting or nah

so I only regularly smoke weed but rarely I'll dabble in benzos. But i recently had the idea to look for something more..and i found 100mg trazadone (it's for my dogs) and i cut half of the pill in half and snorted it all in like 30min.and that was on Sunday (it's Thursday at the time of this) but my throat feels weird almost like strep but not.
