>I noticed the problems that I fought with for ages, that I spent hours with debugging and shit. It just created in 15 minutes. So I was wondering, was I even ever able to code? Or was it just a huge waste of time?

I think it's fair to say that you were able to code in the first place. Yes, you took more time, but if you were able to meet your deadlines and produce decent code, that's what matters.

A more apt question could be: are you able to code right now? Challenge yourself to a small project, maybe in a weekend at most. Do not use AI tools at all. If you can write a small project in the language you are most familiar with, you can still code, even if you need 5x more time.
