Mastitis question

[Cloverbud]

Suffice it to say, I know a lot more about goats than I did five months ago, and it's still not enough.

I have a 5-6 year old Saanen/Nubian, kidded last week with triplet bucklings. No one was home (work, etc.) and they all died. I know I should have had a due date, but the buck got through the fence, which has since been rectified.

I was just going to dry her up and try again next year, but now she's got mastitis in one side. She is a rack of bones since kidding.

Do I a.)treat her, fatten her, and keep her with horrible feet that I've been correcting since I got her last August, b.) treat her, fatten her, and send her to freezer camp, or c.) shoot her and dig a hole?

If she is CAE positive and I raise on prevention, does that have any bearing on your answer?

Please keep in mind that this is my first kidding season, my learning curve is kinda steep, and I've been pretty frazzled. Tell me straight, but please be kind. I'm trying my best and just want to make the most of a crappy situation as I work my way out of it.
