Same thing on my project. Thousands of lines across a few dozen files copied 100+ times. At that point there’s almost no going back with everything diverging so long ago.

Are you familiar with neocities (geocities revival thing)? It’s not anti-scripting but it may scratch your itch.

If your school has Hackathons, try to do those, ideally with friends. The atmosphere is honestly a bit horrible in my opinion and you may get instant imposter syndrome, but it gives you a project to talk about.
