am i a bad friend?

my friends are extroverts and they like outdoorsy activities like just hanging out and going out and i’m an introvert and a homebody person and since its vacation its my comfort staying in the house and not leaving, i go out with them sometimes too but other times i really need to stay home cause i don’t have the energy and mental capacity to go out. i feel guilty rejecting them but if i don't prioritize myself too i’m gonna be a lil down. plus i cant force myself since if its decided on my mind then i really don’t want to

its not like i don’t wanna be w them but it’s tiring to socialize sometimes
