Virgo Boss Copying Me! How do I stop this?

My Virgo boss has repeatedly stole my ideas and work and claimed it as her own to other co-workers and our bosses. Virgos, please tell me how do I make this stop and get credit for what I've done?

You can't stop what she'll be inclined to do. So start speaking up and out about your own ideas--let whoever you want to know, know before she does.

I mean, you probably can stop her but I doubt it'll be in a good way that'll make you feel any better.
