Waking up in the middle of the night-help!

We recently transitioned our daughter from our bed to her own toddler bed or her bedroom floor depending on her mood.  It took 2 weeks to get from our bed to her room with me sleeping on the floor in her room since she would wake up through the night calling for me so it seemed like the right thing to do so she would be assured I was there.  Over the weekend she would fall asleep and I was able to escape to my own bed however the last 3 days have been so disturbing.  She wakes up 3 to 4 times a night screaming at the top of her lungs and refuses to lay or sit.  She wants me to stand up and hold her which doesn't last long because she weights too much to hold like that for a period of time which then causes more screaming and crying and a battle to convince her to sit or lay down anywhere. I just don't know what to do anymore.  Gave in last night and put her back in our bed after all the hysteria and she did not wake up once. Anyone with advice would be helpful and appreciated.  I am to the point where I'm crying right along with her in the middle of the night.  Thank you.  She will be 2 at the end of the month.
