returning puppy feelings

was anyone else really reluctant to return their puppy even tho they had BAD puppy blues? i feel so bad for returning my 10 week border collie and its only been a week. i’m still young and idk why my parents agreed to me having a puppy, the sudden change in my routine stressed me out a crap ton since i’m already terrible with change. don’t get me wrong, i love my puppy but the constant biting, pooping and peeing everywhere is really starting to get me. everyday i would get at least 6k steps from taking care of my puppy alone. i also put a ton of pressure on myself, to train my dog the absolute best and make sure he doesn’t have any health issues. another reason why i wanna return him is because i can’t handle seeing another one of my pets die again, even tho i know dogs don’t die until like a decade later. did any other puppy parent return their dog and how did it feel? how were you able to cope with the emotions and should i wait longer to see if i actually wanna keep the dog? i do really love him
