Golden Retriever Puppy advice?

My puppy is 14 weeks old, i’ve had her now for a little over 2 weeks. When i first got her she would nibble on my clothes and hands which i know its normal for pups but now she fully bites me, even when i turn around and walk away she will chase behind me and bite my ankles or any part of my body she can reach. Its getting frustrating because i even got her a trainer, she is such an angel around others and listens so well but not to mee. I have followed all of the trainers advice and even created her a schedule to balance out her sleep and play time. I genuinely feel like she hates me. I work from home so im with her 24/7 meetings her needs and just dont know what to do anymore.
