I wanted to paint over my bathroom. The paint was peeling and coming off in large plastic-like strips. I assumed that I could not paint over it, so I ripped off all the peeling paint. It seems some drywall came with because afterwards half the wall was brown paper. I tried putting primer over it but that made it worse and now the wall is really uneven. What do I do?
You'll need to patch the areas, where the paper tore off, and then skim coat the entire wall, so that the patched areas, don't stand out "shinier and flatter", than the rest of the wall.
At this point, Google is your friend, especially if you plan to fix it yourself. You may also be able to get a contractor, to do the whole thing, for a fairly cheap price. Prepping a bathroom for paint, is beer money for some guys.
Research, research, research!
