Incredibly triggered

feel incredibly triggered. not sure what this is all about. my head hurts and my heart is racing. my hands feel incredibly shaky and i feel cold. so very cold. the wind is howling outside and the rain is beating off the windows. usually rain beating off the windows is not a triggering sound but tonight for some reason it is. i want to scream but only silence comes out. my voice is lost, i cant find my words. i think i need to explore this more in therapy tomorrow.
