Yes.
But feel free to hold on to it until that last bit of green disappears.
I do this.
I force myself to look at it so as to etch it into my mind that I shouldn't have ___________. Or if I don't know, have made a list of probable causes. Then I do an autopsy looking to find the evidence and then figure out what I should have done. Once I found evidence in one of my dead trees that let me off the hook, and I still cannot figure out how I could have known about the problem from outside appearances.
So, what did you do that you now suppose you shouldn't have?
If you hurry, you can probably get another (or several more) at end of the season sales so that you can inexpensively do what it takes for you to keep these damn things alive.
Keeping them outside is #1.
Making sure the roots get oxygen (air) is #2 (which means don't drown them).
... keep going ...

btw, my half-sister gifted me with one. It took me two years to kill it. For a time I got much better at it, needing only a month or so to kill a tree. Now, after about a decade, I kill very few (2%?).
