I can resonate with this. What I remind myself when I have these thoughts is:
A) Life is like an evolving game with many rounds. Some doors close in your 20s, other doors open in 30s and so on. See what interests you outside and off the screen, once you find this, connect with other people who like to do it. For eg. in my city a lot of tech workers are into bouldering and hiking. You will see as you make friends in your age group, there is a whole bunch of new doors opening now that you are in your 30s.
B) Actually most of the things you list are totally still doable even _if_ you did want to do them. School as a typical student maybe not, but why be typical? I've met backpackers in their 60s, age truly is just a number.
