If Sally is on the receiving end of hatred, she is hated.
If Sally is on the receiving end of a grudge, she is resented.
To describe the situation from Sally's perspective:
Alice has a grudge against me.
Alice resents me.
This is because a "grudge" is itself a specific kind of resentment based on grievance.
Sally might also be shunned, disdained, scorned, snubbed, etc., but resentment is the general emotional stance of the "grudge-er" towards the "grudge-ee" (not real words). This is true for a powerful grudge or a mild one; unlike hatred, which can have any justification, a grudge implies that a person was specifically wronged. A powerful grudge might also be described as a desire for revenge or vengeance; then the "revenge-ee" (not a real word) might be described according to their specific wrongdoing: "my attacker," "my oppressor," etc. From Sally's perspective: "Alice wants revenge on me."
Note that "begrudge" is a related word, but it takes an object -- either something that is worthy of envy or something that will not be shared. So Alice resents Sally, but she does not "begrudge Sally" -- instead, "Alice begrudges Sally the award." Again, from Sally's perspective:
Alice begrudges giving me the award.
