You should never do that. This is the official Manjaro support forum, so this is the place where you should have come for information — and just for the record, there are various threads here about blurred fonts and blurred icons, which is why I suggested the most likely culprits for that sort of issue.
Well, in this particular case, it wasn’t the A.I. that gave you the wrong instructions — it actually gave you a correct one — but you adding a space in there. A space is a so-called field separator, even in regular human writing.

But you blindly ran the command without knowing what it does or how to use it — hint: every command in a UNIX system has a manual, a so-called man page, which tells you what it is and how you should use it. The command you issued by inserting that space was “Recursively remove everything in my home directory without asking for confirmation.”
rm = remove/delete
-r = recursively
-f = force (i.e. no confirmation)
~/ = your home directory
I think we all understand that much.
Well, I hate to have to be cynical here and now, given the loss of your data, and I don’t want to sound condescending, but Manjaro really isn’t a distribution for absolute beginners, notwithstanding that it has — for commercial reasons — been profiled as such in the past in a misguided attempt to lure more people into installing and running Manjaro.
I’ve written a (not too long) essay on this subject, several years ago now, and you may not be in the right mindset right now to read it, given that you’ve got a bigger problem on your hands, but I’ll post the link below anyway, just for reference. 
Now, as an additional piece of advice, do yourself a favor and seek out a computer store near you, and purchase an external HDD or SSD which you can connect to your system via USB. SSDs are expensive now due to the market responding to the storage greed of A.I. systems, but you should be able to pick up a 4 TiB spinning hard disk drive for little money — it’ll be slower, but just as reliable as a storage medium.
Create an ext4 filesystem on it, mount it, and then copy over either your entire home directory, or at the very least your ~/Documents, ~/Downloads, ~/Music, ~/Pictures, ~/Projects, ~/Video and ~/Templates directories onto it every day. There are software solutions in the repository to help you do this sort of thing very easily, with version numbers or dates and times added to the folders, so that you can keep multiple iterations backed up side by side.
Make it a habit of doing this every day when you log off for the night, and after copying the stuff over, unmount the device again, power it off, and pull out the USB cable, so that the device is truly disconnected from your computer and that your data will thus be safe.
