Do you think I will regret selling my possessions and living on the necessities?

I have been going through this stage where where I am selling most of my stuff & just live on absolute basics under the motto things I love & things I need only. Have you done this? Do you think I will regret it? What is this a sign of?

Its bizzarre but I neeeeed to get rid of my ‘stuff’. Is this a stage in life? Im late 20s am I having a nearly 30 crisis or something? Anyone eles done this ever? Did you feel better or did you regret it? Literally my sofa, tv, most books, some clothes are all on trademe or at the charity shop!! Im feeling content with this at the moment but wonder if I will wish I hadnt!
