Feeling Paranoid and Hearing Voices

i think something is wrong. Time has been going by so fast. i’ve been incredibly paranoid since around 2 days ago and yesterday i kept hearing ppl yelling my name while i was at work. i couldn’t look at my reflection in the mirror while i brushed my teeth bc it rly freaked me out and i was scared i was gonna look at myself and see or hallucinate something really horrible. i kept thinking ppl at work were laughing at me, talking ab me and like planning against me. like they’re gonna pull out a gun once they pull up to the window and shoot me or they’re gonna follow me home after work. I had a lot of other weird thoughts that made no sense but my thoughts are so loud and like racing in my head.
