I received a Peace Lily for my mother's funeral 10 months ago. We have a love/ hate relationship, and I am desperately trying to save it. It sits in my office, I water it once a week (not too much), and gets adequate sunlight (but I live in IL, so it is sometimes cool and cloudy in the winter). Our office has a pretty comfortable temperature. It constantly gets new leaves, but then the ends burn until the whole leaf is brown. I tried not to cut them off, but the whole plant was almost destroyed, so I started to prune it back to make it look better.

I haven't fertilized it for 6 months, thinking I shouldn't make matters worse. It had a bloom, but it died too.

Any advice would be helpful. Thanks!
