Have you hit one of those "0" birthdays yet that really bothered you? Perhaps the age contained a "5" rather than a "0." It seems we all get to one sooner or later that stops us in our tracks.
I breezed through several of the "0" ones with no problem—in fact, embracing the prospect of getting closer to that wise-woman stage. But then I hit one that really zonked me. At least for a while. I'm past that now—and see that age as simply a number, not necessarily indicative of anything. I'm trying to make the best of each age and just keep doing what I want to do. Maybe even learning new things as I go.
You and I face physical and hormonal changes, however, that we can't ignore. Are you going through some of those right now? Noticing that you don't bounce back as quickly from a string of late nights? Or sighing when you notice those smaller clothes at the back of your closet that no longer fit? Maybe it's your changing libido? Or it's finding hairs in places you never saw them before!
How do you come to terms with these changes and with your aging process? Do you ignore it? Embrace it? Grieve the losses—and then move on?
I encourage you to find a way that allows you to move on without too much looking back. What has helped me is noting the losses that I perceive, talking about them, grieving them and then letting go. Sometimes I have to let go again when I feel the loss later. That's OK. It still helps me move forward. It has also helped me to talk this over with friends, counselors and coaches. Do whatever helps you. And then go out to meet life with a spring in your step and joy in your heart! As the saying goes, "Age is a matter of the mind. If you don't mind, it doesn't matter!"
