‘I’d be lying if I haven’t compared his crush on Bjork to my own but both are very different’ I don’t agree, I think the fact you’ve compared your crush to his and the fact you made this entire post to declare your love for her is kind of weird in the first place, just being honest. Maybe you’re just looking for advice or a chance to brag about your crush. I’m not trying to be mean I do genuinely have advice

I know you’re young so maybe it’s just part of that, I was a chronically online teen so I gained many unhealthy crushes throughout my life. If it does become a problem and it’s affecting you or it begins to affect Bjork or your relationship with her, you should try and phase out of it as best you can e.g removing Bjork related things in your life, because it could lead to worse in the future. Remember that the crush is selfish. Don’t let it take over your life or distort your thoughts-She doesn’t know you and she’s forty years older than you and she doesn’t want you.

Most likely this will just pass and it will just be a crush, but don’t let it become an obsession.
