Try not to focus on "feelings." They come and go. I don't necessarily "feel" like going to work everyday, but discipline myself and just do it.. I could analyze myself to death about why I don't feel like it everyday and it would just run me in circles and get me more worried about how I feel each day than just getting up and going.
Works the same with detachment. Focusing on the feelings is futile. Focus on the discipline of doing the things detachment requires. Some days you won't feel like detaching. Detach anyway. Some days you do feel like it.
