How long will this last

I lost my best friend back in mid July to early August. They just blocked me out of nowhere on everything, even Xbox. Also when I said out of nowhere I mean nowhere, we hadn’t had a fight or anything. But it’s been going on over a month since I lost her and I still miss her. And I just don’t understand how long this’ll last.

Note 1: we had had a fight early July but had worked it out or so I thought. She blocked me almost a month after it so idk if it’s related.

Note: she’s from the UK I’m from the US so online was our only way of communication. Also we had known each other for a little under a year when she blocked me.
