I feel like I've finally tipped over the edge. I had days, weeks of nausea before, but this time I can't bounce back. I try to eat, but can just get a couple mouthfuls in before my stomach reacts and says, "no more!"

How do I get better? I'm so weak that all I can do is sit and read. I can't concentrate on anything else. I pick and pick and pick at my nails.

How do I fix this?
