I'm sure you've already had your eye on another one... it's possible.
I've sold a lot of things, some I've donated to those in need. Of the things I have sold, I do regret some, but I couldn't do otherwise. Examples would be my computer specially built for design that also included 3D design, powerful. My brother built it for me, he is a technician. And then my drawing tablet, my painting stands. In this last case I have one I have replaced, it couldn't be otherwise!!!!
I have my eye on many things, some I shall get and some not. Regret is easy to overcome when it's about material items, it's when the regret pertains to other matters that things get more difficult.
Some things don't come back... yes, that regret is much more complicated.
