Missy is definitely feeling bad, which is why she is hiding. The brown vomit is somewhat concerning and indicates that she has some sort of irritation to her stomach. This can indicate an infection, blockage or toxin reaction within the stomach and/or intestines. It could also be secondary to another disease condition affecting the kidneys, liver or gall bladder. Sometimes these things can be temporary, but I wouldn't wait longer than a day to see if Missy gets better on her own. It would be best for a veterinarian to check her out, so they can determine the cause, and/or at-least give her something to feel better. I hope that helps and Missy gets better soon.
