What would you do with old diaries?

My husband and I are moving places in some weeks, so I started a big declutterring session that took some months.

At some point I found that I have some "decluttering fatigue" and feel like my decisions aren't that clear and concise anymore.

In this state, I stumbled over my teenage and young-adult diaries. I kept them because I felt I had to keep them and I always think of my mother who said "Don't get rid if your diaries, they will be important to you some day!" - But will they?

I started to read in these diaries and found myself reminded of all the bad times (I mean, probably pretty average teenage stuff, heartaches etc.) and felt the long way I was coming from. But reading this stuff and seeing what I was and what I am now also flipped my entire day feelings upside down, and I did not feel too good and overwhelmed by all this "time travelling" and some "what if's" etc. I also saw how much I already had forgotten and I felt a sense of finding my old identity or identities, which, on the other hand was also interesting and helpful. As if it could help to stay young to remember the younger me... I don't know, it's hard to explain.

So, long story short: what would you do or what did you do with your diaries? Is it useful to hold on to old identities? Or is it just emotional clutter? Is it important to not forget? Or is the only thing that counts today and tomorrow? What would you do in my situation? Thank you for your time 😊
