Buying QQQ is easy. Holding through the drops is a whole different thing

I've been holding QQQ for almost four years now. I started buying during the 2022 selloff, so my average cost is still pretty good. I'm still up overall. I'm not actually losing money here. But after this recent pullback, a huge chunk of my unrealized gains disappeared in what felt like no time. That's the part I wasn't really prepared for. People always say if you're holding QQQ for the long term, just ignore the noise. And logically I get it. The index has recovered from plenty of corrections before. Emotionally, though, it's different. Watching my unrealized P&L on moomoo go from green to red over a few days felt way worse than I expected, even though I'm still comfortably green overall. In some ways, it almost feels worse than being down early in the position because you've already gotten used to seeing those gains. I've always been a pretty passive investor. I buy, keep adding, and mostly ignore the day-to-day moves. I don't spend much time looking at what's driving the moves or whether this pullback is just another correction or something more meaningful. When it's going up, I feel smart. When it's dropping, I basically rely on faith. Maybe that's just part of long-term investing, but sometimes I wonder if there's a better way to handle it mentally. For those of you who've been holding QQQ for years, what actually helps you stay calm during drawdowns? Do you just stop looking at your account, or do you actually watch certain things that help you tell the difference between a normal correction and something more serious?
