HELP! MY NEP MAY DYING! :((

[Zawert]

Today I gave my Nepenthes Rebecca Soper a lot of water. Only sprayed on it with a water-sprayer thing. But when I came to pick it up 2 hours later I saw that one of the pitchers leaf (the one they use to block for rainwater) was pretty folded. It was bend down and seemed to be a little more weak or thin than it used to.

Can I do something to help my plant? What can I've done wrong? is it actually normal for Nepenthes to let some of the pitchers die or what? On my plant there's a lot of new pitchers to come, but I've not had it for so long so I don't know what's going on.

When I got it, there was a dried old pitcher hanging from the plant. I cut it off. Is this normal, and will the plant just live on?

Please help me, cause I don't want my Nepenthes to die..
