Isn't it awful to try to wake up from nightmares?

I dream constantly about trying in vain to save my mother from dying (she is deceased).

And I often dream that I'm in a crisis and my family, especially my sister but often my parents, ignore me, don't support me or often directly undermine and sabotage me. Or I am invisible and no one can see or hear me, or if they can, they choose to turn away and not acknowledge my existence. In my case, I understand these dreams, unfortunately, they have a pretty literal translation to reality.

I want to wake up but keep dreaming. Then when I finally make myself wake up, I have to get up and shake it off.

I am sorry this is happening to you. You're not alone. I don't know of a remedy to offer you. The sub/unconscious mind can be pretty cruel. I sincerely believe that sleep should be an opportunity for peace.
