Personal lost media?

My old diaries and art. My family moved a lot and it was hard to hold onto a lot of stuff (my parent would also "make" things disappear sadly). Tons of art-again, if parent didn't like it, it "disappeared" while I was out at school.
Some sample anime DVDs I had from magazines-I used to sneak them when my parent wasn't home, some anime handouts. I hid as best I could but parent eventually found those too.
Also this really cool "animal dictionary" thing I made with fancy magazine clippings. I was quite animal crazy as a kid and even wanted to be a "archeologist" or "paleontologist," misspelled since I was like 6 of course. Finally, some Seuss themed book called like "All About Me" or something like that. Similar to my diaries.

Well there was a lot of weird videos that I did over the years on my devices that I couldn’t save or deleted for reasons

Wow that really sucks, as bad as my dad could be he never personally went after any of my stuff(probably cause he knew if he did i'd mess with his stuff too out of spite and he had a lot of dangerous stuff like guns and chemicals that wasn't meant for kids to be around and if I did mess with it mom would've been pissed at both of us) and i'm very grateful that i've never once had to move and i'm still living in the same house I was born in(same bedroom too).

It seems strangely wistful and personal, but the old text messages/emails between my first "major boyfriend" and me. It was an older phone, I didn't back anything up (and I'm pretty sure he didn't) and we've been no contact for over 10 years now. I was just thinking of the fun long distance conversations we would have. No, I'm not stuck on him, I'm not pining for him, I'm not hoping to rekindle anything, I'm not still "missing him" or anything like that, I just got a certain vibe from our interactions and it would be fun to see what we rascals were up to then. Ain't never being found though.

I have some my first 3D renders of the Blender donut tutorial I was doing somewhere on the various hard drives in my house. I feel I should keep them as a keepsake.

In the mid 2000s, I was working on a game in Unreal engine I called "E.L.I.T.E" (I don't remember what the acronym stood for) but it involved an organisation trying to help restore things after an accidental pandemic that was caused when a lab exploded, flooding the air with a contagious pathogen. I had made several maps in the game for places including Paris in France, China, a base in Antarctica and had plans for Japan levels and drivable vehicles. I wrote an tire backstory for it and storyline and had even made a number of assets for the game.

I ended up shelving the game at the time as my PC wasn't really fast enough to create the game and I didn't have enough coding skills to do all I wanted. I was going to start working on it when I had a faster PC and more coding experience but I eventually lost 99% of it, including the modified Unreal Engine 2 editor I was using to make the game. I just have a few textures, meshes and a couple of unfinished music tracker files I made. 

I also had a year or mores worth of photos and videos I took in 2009 on an external hard drive that stopped working. As I didn't back it up, I lost all of those and whatever other files were on the drive. I was helping to do research on butterfly migration at the time and would have liked to have kept those files. Since then, I have been really careful about backing up everything so that doesn't happen again.
