Loss aversion is actually significantly powerful and difficult to overcome, but think about why, it's only very recently that humanity can easily procure anything it needs for survival with relative ease in most countries. While getting something new is exciting losing something is far harder when you never know when/if your going to be able to gain it again. It's helped humans survive throughout our history, so I wouldn't be hard on yourself that it wasn't easy to detach, you were just practicing a survival skill.
