Feeling Despondent Again

Why does it seem like my classmates who are as far away from getting their MSN as me (5 months away) are able to secure jobs in their area that they originally went to school for, but I'm not?

I've just been totally frustrated with job-searching lately and it's wearing on my self-esteem.

For one, I'm working in a position that has allowed me to lose my OB/GYN focus, because I'm so generalized and no matter how much I try to capture that back, am just not allowed to in this position. Secondly, my boss has all of us doing more administrative support work (photocopying, reserving rooms) for our clients that I have nothing of value to really put on my resume. I've been in this position now for 1.5 years.

I've applied for jobs that were higher level leadership, been interviewed but turned down, probably due to my lack of OB focus (the person they hired had more recent OB focused experience than me)

At the same time, I've applied for jobs that are on par with or even LESS than my position now, and I haven't gotten interviewed.

Even yet, I just applied for (24 hours ago) a position in Community Ed (more generalized, but patient focused, which is what I want) and got turned down even for an interview, though the position wants a BSN but prefers an MSN.

Is it my resume? I just don't understand. I feel so trapped in a job that's not even helping to advance my skill set and there's nothing I seem to be able to do about it.
