Everyone has bad days. You cannot avoid them. Sometimes, it is a bad month. Or a bad year. That is life. I guarantee that at some point, if not several points in your life, you will be brought to your knees by something. So, given that that is a certainty, the real question is how do you handle it? You need resources.
Resources can be a variety of things. People who love you and support you are a very important resource. Knowing that there is someone who will hold you and listen to you and support you is priceless and can get you through almost anything.
Your spirituality is another priceless resource. We need to connect to something, whether it is through organized religion or nature, but something that helps to soothe our soul and helps us to make sense of things.
Exercise gives us endorphins and energy. Meditation settles our brain. Journaling gives us a place to vent. Our animals give us unconditional love. Books and TV and Internet give us a temporary escape. And there are so many other options and resources out there.
Resources are very personal. What works for me may not work for you and vice versa. But, it is crucial that you have a list of resources that you practice on a regular basis so that you have them as you need them. It is important that you write this resource list down and post it some place that you will see it so that when you are overwhelmed you do not need to think or remember what your resources are; you can simply look at your list and be reminded.
We can survive what life throws at us, as long as we have our resources!
