am I being frozen out?

I was wondering if what I am feeling is just paranoia or if I may be on to something. I have been getting the sense in the past few weeks that my stock as an employee in our company has fallen dramatically. My boss hasn't mentioned anything to me nor has anyone else. I am just getting this feeling because:

1) In meetings whereas before I felt certain people listened to me and took what I said seriously, now I feel like they are cutting me off mid-sentence whenever I speak.
2) People higher up than me are either not showing up or canceling meetings with me on projects I am working on.
3) I feel like I am not privy to important decisions and information being passed around on projects and am not included in "unofficial" meetings after hours, behind closed doors, etc.

I'm a midlevel technical person. I am not a director. So perhaps I shouldn't feel as if I am being slighted here since I am not a boss. But then again, how come I have this pervasive feeling that I have fallen out of favor among people I work with?

I have regular weekly update meeting with my boss. Are these type of issues appropriate to discuss with her or do I risk being perceived as a whiner in addition to the other stuff?

Talk to your boss. I'm glad your instinct is to ask about this candidly rather than to worry privately, and I would definitely want you to raise it if I were your boss -- so that I could either reassure you if there's no issue or use it as an opening to talk if there is. However, in the interests of not sounding too paranoid if indeed this is all inconsequential, I'd tone it down a little. Consider that you might be completely wrong and that what you're noticing isn't about you at all (but rather about situations that have nothing to do with you), and allow that possibility to inform your tone when you raise this. Good luck, and please let us know how it goes!
