up in smoke

i’m sitting here and i think i might be going crazy or having a seizure or maybe both but i can smell this burning smell (either like melting plastic or the first time you turn your heater on in the winter… i can’t decide) and no one else seems to be bothered by it! i even asked if they could smell the burning and they said no. might it be in my head? like actually inside my head? my brain burning up from thinking to hard?
