A closet or other room without windows will work. Wait until dark, turn out the lights in whatever adjacent room, close yourself in the closet and proceed.
If that won't work, cover yourself under heavy blankets on your bed with the lights out (at night, also) and load the film.
I've used this method many times in hotel rooms and such when I forgot a changing bag.
If you have a room mate they may think you're weird, but that's ok, lots of people think film lovers are weird
, they will get used to it.
If handling this film for loading + subsequent processing will be a habit, a changing bag will give you portable darkness you can use anywhere anytime.
And, welcome to the club!
