In situations like this, its normal to think that your own behavior is faultless, and that the "others" are conspiring to screw you over.

In reality, its usually you that is the problem. For whatever reason, the people in power don't view you as a key player. They may even be hoping you'll leave.

Situations like this are pretty much unrecoverable, so best to look for another job.

But, do think hard about where you went wrong, so that the same thing doesn't happen again.
