Notes on my Peace Lily

My peace lily (Spathiphyllum wallisii) has been drooping like crazy even though I water it regularly, and I'm genuinely confused about what's wrong. I read that they're supposed to be forgiving, but mine seems determined to test my patience. I'm wondering if it's a humidity thing since I live in a pretty dry climate? Has anyone else struggled with getting theirs to actually thrive, or am I just doing something obviously wrong?
