Hello everyone!

I need help with my fitting. I have a new road bike and I've replaced the stem to try and get a better position and something went horribly wrong. All my weight seems to be in the front, and my hands are taking a beating. My center of gravity also seems a bit off. I've included a picture for review. Just from the picture, any hypotheses as to what my problem is?

Thanks so much for the help!
Coco
