The real wisdom here isn't that suffering stays manageable—it's that our capacity itself *expands* through trial, that we're not fixed vessels slowly filling to the brim. A parent who thought themselves incapable of patience discovers reserves of it when their child falls gravely ill; a person facing financial ruin finds they can endure what they'd have sworn would break them. What the Quran suggests is that hardship and capacity arrive together, not that one is simply measured against a pre-existing limit. It's a quieter kind of hope than "everything will be fine"—instead, it promises that when difficulty comes, you'll discover you're larger than you knew.
