Can’t take it anymore

Hello there, I live in a tiny room with large windows. While nice in the summer, it gets really cold in the winter. There are cold drafts near the windows and I'm guessing that's where all the heat is escaping. I would like to find a cheap way to seal them, or to prevent further heat loss. Any ideas/suggestions? Thanks.
