That's a little over dramatic, don't you think?
Sorry if that sounds a little harsh, but I'm afraid your approach is only a setup for heartbreak. You can't avoid the canon, unless you want to just quit the entire fandom, so why get upset about it?
Yes, there was a time I screamed and threw things when my favorite couple didn't get together in whatever series I was into at the time. But over time I realized something: You get over it. And, if you can compartmentalize your own thinking enough to go: "Okay, this is what I wanted to happen, even though it didn't." then you can still enjoy the series.
