RIP your inbox lol. Like others have said though whatever you choose test it out booting off a USB first, fwiw I’d vote try FedoraKDE, but more importantly I’ll add this:

Whatever you choose it will be different and it will be an adjustment in some capacity, and that’s ok! And don’t be scared of the terminal, always keep back ups just in case but you really can’t fuck up tooooo bad unless you’re using sudo and then just be real careful. Watch a few youtube videos on something like “linux terminal basics” or “bash basics” and follow along like you’re taking a class, it’ll really help you get familiar with it. It’s a great thing to know how to use, these days if I know how to do it through the terminal I usually will instead of puttering through a gui honestly.
