Traumatic Experience at Mental Hospital

i had a slightly traumatic experience while at the mental hospital. it was my last day there so i was too excited to sleep all too well. took a trazadone. worst mistake ever; i was super anxious and overstimulated. could not stop moving at all and no matter how hard i tried, i couldn't sleep. i would get up, go to watch tv, come back, and every time i wore my cpap machine it would feel like i was choking. i know it isn't as intense as other, more superlative experiences but it affected me so much i have become afraid to sleep the past few days.
