You headed behind me - Tradução em português

Hello, guys.

In the dialogue:

"John: I'm so fed up with the airlines...

Mark: What's new? Flights delayed, crowded airports, not to mention luggage when lost...

John: You know, I haven't had a single good experience flying domestically in probably about a year or so...

Mark: Oh, man, you headed behind me. To me it's getting worse and worse and worse."

So, in Portuguese, what's the context for the translation of you headed behind me?

I think it would be like, "well, join the club" or "I'm having a more hard time than you in this case."

Thoughts?

Many thanx in advance!
