You have discovered the worst nightmare that can face a person removing wall paper---
The paper was installed over raw drywall----no paint---little or no primer----
As you strip you will also be softening up the mud used to tape the walls----sometimes you will gouge or even peal off some of the face of the drywall---
Just keep going--do as little damage as you can----then come back and we will tell you how to seal the damaged drywall and skim coat it----
You job will take longer than you expected---but will look fine after the skim coat---
