Growing Old Isn't Easy

I thought I'd be okay with aging, but I'm not. Every year feels like it chips away at something inside me. My hair is thinning out, my back hurts more each day, and the aches in my joints remind me of how time marches on without stopping for anyone. I miss when I could run around and play tennis all day with no breaks. Now, even walking up a flight of stairs leaves me huffing and puffing. I look at my grandkids playing outside, full of energy, and it makes me feel old and tired in ways that go beyond just the physical. Sometimes, I catch myself wishing I could go back to being young again, but then I remember all the things I've lost along the way. It's hard to hold onto the past when you're moving towards an uncertain future. I know I shouldn't be bitter, but it's tough not to be sometimes.
