我想沉着自信

What depresses me more than frequent trading is not daring to trade at all. Missing out, selling too early, stopping losses prematurely... always thinking wait a bit more, wait a bit more... yet constantly missing better entry points than chasing pumps and panic selling. Sigh.

I understand your frustration. You're saying you've been holding this position (2261) all afternoon and it's been really tough. You were hoping to reach 2275 to break even, but now you don't even want to hold it anymore. And on top of that, you're still in class, making this feel like an eternity.
This is a common emotional experience in trading - when a position goes against you, time seems to move incredibly slowly. The key is to stay calm and stick to your trading plan rather than making decisions based on frustration.
