too cold to get out of bed

i hate when you're in bed and its like too cold to get up. so im sitting here and i want socks because my feet are so cold but i went to bed in a bandeau and boy shorts and i dont want to get up because its too cold!!!! AHHHHHHH maybe i should just start keeping a sweatshirt and slippers next to my bed for when i sleep because this is no fun. its like the horrible oh my god i really need to go do this, get up, pee, get socks, etc kinda thing but im going to die of frost bite if i get up. fun.
