My Puppy Won''t Eat?

I need a little help with my puppy. She is 7-8 weeks old. The first day we got her, she was eating properly. From the next day onwards she stopped eating. The vet said she's fine, just having separation anxiety from her mum and we need to keep feeding her every three hours.

So the day before yesterday, we had to force feed her. Yesterday morning, she ate, but from my hands not from the bowl, then again in the afternoon and evening we had to force feed her with the syringe. Today again I had to force feed her. She started drinking water on her own. She is pooping and urinating fine. She is active as well. I tried changing her food, but she still won't eat it. She won't lick it from my hands either. Her weight is fine too. It's been 5 days since I got her.
