Puppy exhaustion

I cannot have the puppy in my home much longer, I have told the owner so I hope he sees my message today.
Daisy is grumpy (she only tries to play with the puppy a bit in the morning) and she has almost stopped eating. The only way to get her to eat is to give her puppy dry food.
I do not get relaxing time or time to study, which this weekend was going to be all about. I really need to study, I have a seminar and 3 big exams coming up. I do not get any sleep, I get naps- it wakes me up for toilet time every 2 h in the night and then at 7 I have to get up and walk it and clean up in the apartment.
So now I am tired, sick, worried, anxious and haven't gotten anything done at all.
