Rain, Rain, Go Away

So, um, its raining in my bathroom. I guessing this is very bad?

It has been raining here for a few days. Last night was a pretty big storm with lots of wind. Anyway, I got out of the shower and noticed that there was some water drops on the ceiling. I figured they were from Mike and I showering so close together, plus the humidity and rain, so just wiped them away with the towel. A few minutes later, they were back. The whole ceiling is wet and soft. I poked my fingernail into the crack and water came dripping out. Now it is a pretty steady drip, drip, drip of dirty water.

Help!

Update: Ok, put drain hole into sagging plaster to let the water out. Used a ball point pen, it was so soft I didn't need to drill or screw or anything. I got a good flow right between the eyes then filled the waste basket twice in about 20 minutes. It has slowed to a steady drip again.

*sigh* Anybody know how much a bathroom remodel runs these days? How about a good local work force- I have no idea how to do any of this stuff. Take apart a ceiling, fix a roof leak, put everything back together again. Paint. You know, I have never even painted a room before.

So sad, my new van is driving off into the sunset without me....
