illogical

How is it possible to tell my friends that i'm mentally unstable and had a rough night and need some cuddles and don't want to be playfully bullied tomorrow bc it will end in tears and screaming? Also how do i explain them all the different ways i feel like shit and what subjects i wish they avoided. i will start to wear shirts that have trigger warnings written on them: "don't talk to me about eating disorders, bikinis or working out"
