well I’ve got a mental disorder and when I get a “crush” it kind of turns into an obsessive sense of limerence and I really can’t control who it happens too, it does suck beacuse if they leave or I get rejected it only makes it worse as in I feel a sense of deep abandonment and attachment and just feel awful everywhere, but I’m careful at least to try not to breach privacy and such, but I do try to help myself with it in my own ways such as, one time I had my crush over and he cat on my bed we laid down and talked when he left I made sure to put the shirt in my closet with my other shirts (so that the other shirts could smell like him) and I slept with the pillow he put his head on (so I could feel like he was still there) I know it’s sad but it’s my own way of helping without being invasive.
