You just make a choice and do it. There is no secret aside from forcing yourself to not go there. Like any other activity/habit/muscle...the more you do it, the easier it gets to do.
I suspect that if you're anything like me, you're making excuses re: "don't know how to do that". It's not about not knowing how.
I'm guessing (just guessing!) that the truth is more like, You don't want to let go, therefore you're not.
Again, not trying to be harsh...but I've been there/done that so I know how it hurts and how it feels.
