I cant sleep with people awake in the room and its stressing me out

Im on holiday at the moment and sharing a guest room with my brother and dad. my dad literally wonr sleep until it is light outside which im not blaming him for but im so exhausted and i really want to sleep but every time i start dosing off i get so frustrated i cant sleep. im autistic and i really hate mouth noises (like heavy breathing, chewing swallowing etc) and my dad also breathes tbroigh his mouth which makes me feel like vomiting . to top it off im sharing a bed with my brother which wouldnt be a terrible thing on its own but its unbearable with my dad herw too. its 4am and i just wanna sleep so bad and i cant but i cant be angry at my family cus its not their fault and they dont mean to.

Also i hate sleeping in certain clothes and since im the only girl in thw room its really awkward getting changed and i didnt get a chance to so im having to sleep in my normal clothes which is gross for me and it feels so itchy
