Going away for a long while without my hamster, what to do???

IM STRESSSING OUT RN. Im leaving for the UK in a week for 22 days and I cannot for the life of me find my hamster a caretaker. Most the people I asked dont wants to take up the responsibility, everyone's parents said no and some just dont have time or are out for the holiday. I dont want to leave my poor baby at home all alone, what if something happens to him and im not around?? I tried finding some online but I live in a small town so the pet sitter are mostly for dogs and cars only. I'll try searching some more, I dont know what im gonna do if I can't find one
