I can try to change my negative thinking, that would probably help, as well as stop obsessing about my marriage.
This is an excellent step.
It is also easier said than done.
Goals of action, like biking, volunteering, rock climbing...
Having dinner with friends...
Are easier and a little bit more concrete.
The result of those sorts of thing, should eventually lead to the goal of stopping negative thinking or at least obsessing about your marriage. For the most part anyway.
A good reminder to help stop the negative self talk, is to wear a rubber band around your wrist. Snap it each time you have a negative thought. And change the thought to something positive. Sounds a little bit self punishing, and maybe it is, but you just might find that you want to avoid that pain enough to change your thoughts.
I think it is Grace over in MLC who describes this much better than I do.
Maybe someone around here can give you a better description. LOL
