Learn How to Leave a Fandom

1 Like Alcoholics Anonymous, you have to realize your issue and what your goals are.

2 Refrain from spending time on your fandom. Whether you collect fandom items, browse the internet for fandom related items, or dress or act like characters in your fandom, slowly remove one activity at a time. Start by shaving off the easiest activities to get rid of and gradually raise the bar.

3 Find something else to occupy yourself. Spend more time studying, reading other books you never got to, learn a new sport. The more time you spend doing other things the less time you will spend in and around your fandom community and activities.
