Ever find yourself saying, "I'll do it later" only to find that "later" never comes? I had an experience a few years ago where I kept putting off something because I just didn't want to be bothered. I told myself, "I can handle it!" "It's no big deal." Well, eventually that "no big deal" turned out to be Stage 2 uterine cancer. It was a big deal. My ignoring the symptoms did not make them go away. I finally had to deal with it.
We do the same thing with our mental health. "It happened so long ago, I've forgotten it." "I can't do anything about it now so might just as well get over it." The only problem with handling our hurts like that is they just continue to fester, like a cancer. Our hurts have to be addressed so that we can be healed and move on to a healthier existence. Don't put off to tomorrow what you need to address today.
