/big hugs! I'm so sorry! :( You should definitely delay Shipswap for a little while at least. I mean, anyone who complained about having to wait a little longer when you're going through such a tough time and can barely even access it without pain would just be an asshole. You definitely need time to get better and at least get back to a computer which doesn't give you massive headaches.

Is there any way you can talk to your prof. and negotiate it? Or can you use another computer like a friend's, or a library one? There's office online http://office.microsoft.com/en-us/online/
