Is it normal that I am 15 and extremely hate my parents to the point of me verbally abusing them because of them not accepting me for who I am?

NO. at the age of 15 you are not so mature enough to decide what's going on .parents are always caring and our well wisher. after being mature your perception changes for parents.

I understand having these very strong feelings about your parents. It is normal to want to distance yourself from your parents in your efforts to feel like you are your own person.

Verbal abuse is not a solution I guess. But I can feel your pain as a victim of family issues. But if you're confident enough, never listen to others. If they have problems then you can't amend all of it. So try to deal as best as you can without hurting anyone's feelings. Hating parents is not a new issue, so I guess it's pretty normal. But abuse is a thing I don't prefer. And you are a teenager still, so you can control it if you wish. Anyway, do your best, be confident, keep fighting. All the best champion.
