Went fully automated after years of semi-discretionary and the losing days hit differently than expected

Summary
The author describes the psychological challenge of transitioning from a semi-discretionary trading system, where they manually filtered entries and overrode exits, to a fully automated one.
Their thesis is that even with a technically sound and properly backtested automated strategy, the emotional experience of losses changes, feeling less collaborative and more imposed by the machine, creating a persistent urge to intervene.
Quality assessment: This is a qualitative discussion about trading psychology and process. It is not well-researched DD, speculation, or noise regarding specific market moves; it is a meta-commentary on system trading.

Curious how others handle the psychological side of switching from discretionary to fully automated trading...specifically around trusting the system when it's losing.
Background: I've been running a semi-discretionary approach for a few years. Entry signals were systematic but I'd filter trades manually based on "feel" and occasionally override exits. Work okay but I was always suspicious of whether my overrides were actually adding value or just giving me something to do.
Spent the last several months converting everything to fully automated. Backtests look reasonable, walk-forward checks out, paper trading behaved close enough to expectations. Went live a few weeks ago with small size.
The strategy has had a couple of losing days since then. Nothing outside of what the backtest would predict. Drawdown is well within expected parameters. But I keep finding myself opening the dashboard and staring at positions like I'm about to do something. I'm not doing anything. But the urge is there constantly.
What's weird is I actually spent time before going live reading track records on dub just to recalibrate my sense of what normal equity curve behavior looks like. Even knowing that flat and choppy periods are just part of it, there's still this itch to intervene when it's your own real money sitting there.
I think part of it is that when I was semi-discretionary, the losses felt like collaborative decisions. Now they just feel like the machine doing something to me.
Anyone else go through this transition and have it feel weirdly harder than expected even when the strategy is technically behaving correctly? And how long before the urge to override starts to fade, if it does?
