Going slowly insane

I think I'm going crazy. I just finished typing the last post, feeling free and easy, thinking I was finally done (for the second night, you'll notice) and I go into the kitchen for a snack and suddenly see lots of little bubbles under the drywall tape where there had never been any before. WTF?!?! It looked like everything was fine and suddenly these things are everywhere. I had a couple yesterday and I slit them open with a razor and put some more mud under them this morning. Those seem to be fine but now there are a bunch more. I am so frustrated!
