I think I know exactly what you are feeling. When I get that way, I feel like I've got this giant load of scream-vomit that is about to burst out at any second if I do not continue to rein it in. It feels like if I could just thrash around throwing a huge fit and let it all out it would be better. And the more I suppress, the worse I feel.

Anyway, I hope you find a way to feel better soon. At least you have a lovely new laptop on the way! And here is hoping that the job related problems ease up, too.
