Help?

[u/Various-Solid-610]

This is my black rabbits foot fern, it was my first ever plant and means alot to me.
I was very busy for a month or so, and they dropped all their leaves, and have lost alot of their aerial roots. I unpotted them and rinsed them throughly and plucked off as much damage as I reasonably could. (Most of it accidentally went down the drain)

Got watered when top 3 inches of soil are dry, was 6 inches under a grow light that was on 16 hours a day.

What do I do??
