Italy here: tap water is drinkable BY LAW, at least inside houses and public places.
You can't go wrong with Debian
I was 17. A teacher of mine was on his day off but decided to came at school and took me of my class only to go to the school cafè and talk. He noticed that i wasn't ok at that time and wanted to let me know that I wasn't alone, and he could help me if I needed him.
Me and this teacher had some fights before (and after) this, but to this day I am really thankful for what he did for me.
Grazie prof
Nobara is Fedora based afaik. I guess you didn't like the Desktop Environment (the look and feel, user interface), not the OS in it's functionality, since all of the distro based work basically the same under the hood.
So: I suggest you to try different DEs, not different OSs. You could try Gnome, KDE, XFCE, i3, there are a lot.
If you still want to stick with distro hopping, then i suggest you these good-looking distros, Ubuntu based:
ZorinOS: looks and feels very similar to windowz
DeepinOS: Very good looking DE
ElementaryOS: kinda looks like MacOS, lacks some software from its store tho
Bonus - Linux Mint Debian Edition (LMDE)
It has a nice interface, modern. But it lack optimization and it looks like it scrolls at 30hz on my 90hz phone, kinda hurts my eyes
Made me smile. Thanks
