IIN I resent my high school days?

I wagged school a lot only sticking around for important classes. I do not recommend wagging. However for me it didn't affect my grades much. It just pissed off my teachers when i ditched. But come parent teachers day, one of my teachers said to my mum that I'd never amount to anything in life right in front of me. All because its not seen as being punctual. And that shit stuck with me ever since. Especially since, the only reason I wagged to begin with had a lot to do with pre-existing depression and anxiety
