Has anyone tried scheduling time for obsessively thinking about a person (or specifically, losing your favorite person)? Did it work/not work? 

Someone mentioned to me that there's this thing called scheduling worry time which is used for anxiety, and suggested maybe I try that out. So it'd be like setting a certain amount of time aside at a certain part of the day to do nothing but think about my ex.  

Had anyone tried that out? I'm worried I'll end up not being able to get out of that space once my time is up. Or that my emotions will build up to the point that I'll feel like I desperately need to talk to him, and end up doing something stupid or essentially harassing my ex by contacting him when he clearly doesn't wish to talk to me :( 



## Background info / possibly not necessary to read 
So I recently got out of a relationship and although I haven't acted as irrational as I have in the past, i still find myself thinking of my ex constantly; which leads to intense emotions.. giving in to my impulses.. ya know the drill, perhaps. I abruptly ended our relationship two times before this third (and final) time. It'd happen when I was feeling incredibly insecure and not thinking clearly. I regretted each time and we worked through it except for most recently. He said he needed space (seems permanently) so I take it he was angry/hurt/fed up. Anyhow. my issue is that I can't stop thinking about him or the situation so it interferes with my friendships and schoolwork, and just life in general. I also have the urge to hook up with someone new, drink, or occasionally self harm.  I've already tried those things to temporarily relieve myself of thoughts of self-hate, sadness and anger. But I'm trying to learn to be by myself without losing it, where the scheduling of "worry" time thing came up.
