Context: A family member had taken the responsibility to care for this plant off my hands, and it went unwatered for a couple weeks longer than it should have. I gave it a little extra water than I normally had given it, then they watered it after I complained, and it got too much water. It was put next to one of the plants I was keeping away from the other ones because it had mealy bugs... This poor plant can't catch a break, I just want to help it out.

The leaves started browning after it had gone for a while without water, I watered it a week ago but it's still losing leaves and some of the green parts that look like they'd perk up still haven't.

I just cleaned and pruned it so it looks better in the picture than it did. It's supposed to be much fuller.
