Stephanie,
I just have to ask you if this thought was more like the "I wish this vacation would never end" kind of thought. You know - you're enjoying the moment and don't want it to end. You know you'll have to go back to your regular life sooner or later, but you don't want to, at least not yet.
If it's that, I'd say that you don't need to keep overthinking it. You were just happy with the moment and had thoughts of it continuing. Not a big deal.
Now if it stirred up deeper feelings that you're struggling with, then yes- go talk to someone.
