No externship = huge disadvantage?

Over the last few weeks, I've been worrying about the future because of the fact that I didn't get an externship this summer. A bunch of people from my nursing program have been updating their Facebook statuses with externship-related things, and I guess I'm just feeling down in the dumps because I'm scared of being behind once the school year starts again. More so, I'm scared of not being able to get a job once I graduate and pass the NCLEX.

I know that worrying isn't productive and that I should focus on the present and the opportunities I do have (I'm employed as a PCT at a local hospital, but I won't get into that because I'm not especially happy there), but I guess a little reassurance from others who experienced a similar situation the summer before they graduated would be nice, haha. And that was the longest sentence ever, sorry!

Anyway, my actual question is, will not having an externship be a huge disadvantage when the time comes to apply for jobs? ("Huge" being the operative word.)

Thanks in advance to anyone who responds! I really appreciate it.
