Same- I wish I died when I was about 10, when I'd just left 5th grade and was so excited for middle school. I was still scared of death back then, so if I died in my sleep, that would be ideal. Compared to now, I was relatively normal back then and my degree of introversion was in the category of shyness, not mental illness like it is now.
I also looked forward to the future so much back then- the only thing I did in my free time was search up colleges and think about what I wanted to be when I grew up. Now I'm scared of the future because I recognize the bad parts too, like the extra responsibility and having to be more mature. As a 10 year old, I usually liked my life and had a lot to look forward to, and if I died back then, I would have had a life consisting of mostly happiness
