She has not been drinking or eating for over a week or so and when is does eat she gets sick

And no engery just wants to sleep allday and very rare that she has to do her thing

Please take her to the vet NOW! she is in bad shape, needs food and water to live.

Why haven't you taken her to the vet? She is suffering!

Sounds very much like my dog Jasper (RIP).

A vet is your only answer. Your dog has no energy because she's not eating or drinking. Frankly I'm shocked that she's still alive if this has been going on for a week now.
