Hello Anthony, there is still hope for your Peace Lily. I have had it worst but it bounced back slowly with careful nurturing. I almost gave up, but I still saw some green then..
Grow it indoors by your window, and water often, it is Spring now so it is growing season. I don't bring my plant outdoors, it cannot stand our dry and hot summer condttions. Watering often does not mean making it swim in water, it still needs to drain properly.
See how bad mine went before and the recovery time it took. Your plant definetely looks much better than mine.
It is Spring now, so your plant will have faster recovery time. Mine suffered during late summer and then I had to attempt recovery going into Fall, just when most houseplants are slowing down due to light duration changes. Thankfully it came back well and good. I did not feed it fertilizer then, it is under too much stress, got to concentrate on helping it recover. Actually I am really bad with fertilizers, so far it still grows nicely indoors.
