You could try getting a couple of books by Vicky Halls, who is one of the UK's top cat behaviourists. Cat Detective and Cat Confidential are probably best. She writes about cats biting and stalking their owners and you may be able to work out what's wrong with your cat. Remember that it isn't your fault, it's just having to learn to understand your cat's particular "language".
However, from the studies I've done in cat behaviour, they always say that biting, especially serious biting is one situation where an experienced professional behaviourist is necessary. If the bites your cat gives you are more than skin deep, or if you've needed antibiotics for an infected bite then it's serious biting. If you can afford it, I'd strongly recommend asking your vet for a referral to an animal behaviourist specialising in cats. Many pet insurers cover this, if your cat is insured you could check the policy.
Your cat will need to be referred by the vet, as that's the only way a properly qualified behaviourist will accept patients. That's because they need to know that the problems aren't caused by a physical illness or pain. Cats are stoics and sometimes the only sign that there's a problem is behaviour. In your case, it doesn't sound as if that's the problem but it needs to be ruled out.
To give you hope that things can change, here's a story from my cat behaviour course. It was an amazing excerpt from a TV programme featuring a cat that was attacking his owner with very deep bites. Top marks to the owner, she'd adopted the cat from the RSPCA about a year earlier and despite being covered in awful scars, she said it wasn't like buying a faulty TV, she loved him and wouldn't send him back. The cat had a known problem with crystals blocking the urethra. The vet said it had come to the point where the owner either had to have the cat PTS or have his male member amputated. The owner chose surgery.
The day after the operation, this very aggressive cat was on the vet's lap, purring and padding. 24 hours earlier, even experienced vet nurses were struggling to handle that cat, they couldn't even open the cage, but here was the vet sitting in the cage with this cat on his lap. A follow up with the owner four weeks later showed that the cat was now a total cuddlebug. He'd just been in so much pain he was terrified of everyone. Once his pain was gone, he showed his true cuddly nature.
