Help

m so fucked up. I mixed weed with some pills this guy gave me I dont know what they were. I have sa much school work to do and im so dizzy I cant stanc and I can barely sit up. I just got home and struggled unlocking the door with my key. I dont know what to do im so stupid. Im getting very twitchy and I like cant control my expressions. And stuff thats like on the ground feels like its coming towards me
