14 years old, but feeling old?

Hi...so lately I've been a little sad cause I saw an old photo album from like 10 years ago of me as an infant...I cried when I saw these pics, and I'm just feeling old. I feel like the past decade has gone by way too fast...I know I have a whole life ahead of me, but idk, I'm feeling nostalgic guess? I'm only 14 years old, but I feel like I'm on my deathbed looking back at my entire life. Anyone can help me feel better?
