You can always start again. Clean out your social media. Create a new account for your new taste in music. Study or work in a new city. Start socialising with new people. Choose a new signature scent and style and purge the outdated parts of yourself. If you don’t like where you’re at, but you don’t know what to do about it - try starting again.
one thing i realized a while ago is that some crushes are better left as crushes. sometimes, you only like someone because you don’t know enough about them to dislike them.
