So this is kind of embarrassing but…

[4Kingdoms]

Was wondering if there was a sub That could help someone get over an unhealthy infatuation or “crush”.

I know there is a sub to help get over past relationships, but this is someone I never dated. So I’m not sure if that applies.

I am also wondering if this may indicate that I have something to heal from. I’ve considered trying to run E3 but have also considered Aura of Love as I have heard good things about that one as well.

Any suggestions?

There is nothing to be embarrassed about. 
I'm not able to suggest a specific sub because I haven't used a sub for your current situation.

There are, however, multiple YouTube videos on this topic.  Watch a few and find one that resonates with you.
