maybe you can try buying a mini freezer and placing it in your room? I hate to be dishonest but sometimes white lies can help, for eg you can explain that your friend gave you this as a present so in order not to waste it, you'll use it to store your milk 😜
btw I totally feel you. it's so tiring and sometimes painful to pump, plus you have to keep washing the pumps etc. when my baby couldn't finish, I was already feeling the heartache for a long time. not to mention if people threw unused packs of milk away... all the best though, hope it works out well soon!
