I have painted my bathroom too many times. I hate the color it is right now, and there are a bunch of problems with the walls that I have caused. In the pictures you can see a part right above the tile that is totally scraped down to below the wall itself, and there are two big spots where I had peeled off old paint, thinking that would be the smart thing to do, but now the wall is uneven and stupid. I have tried sanding those areas, but it didn't do anything. Also, the paint around the shower is peeling up. There is also a picture of that. How do I fix all of these problems? The pictures probably do a better job of explaining than I do. Please help!
