Well, after reading most of the posts here I have to agree with most everything.
One bit of advice though, if you start making changes either to your diet, or hers, do one thing at a time so you know what, if anything makes her better.
I would also reccomend looking into this

There are other things on the market that can help if this is not available to you.
There is so much that can overload a new mother, and the biggest thing she needs is the support of her friends and family. Reach out to them. The housework can wait ( mine still is on hold and my kids are 18, 13, and 11 ). It's just not important. I would still consider speaking with your Dr. He/she should know what is going on. Listen to what they say, and make a judgment call. If this behavior continues with her months down the road, it might be more than colic, and the Dr. will need to have that on record. He's not going to want to hear about it when she's 1 for the first time....
Anyway, keep us posted, good luck and if you ever get to your breaking point, walk away and call someone to give you a break, we have ALL been there, trust me on that. I'm not saying you would ever hurt your baby, it's just a very tough thing to deal with, and we all break down somehow or another.
