Is it normal for me to hate my family?

I'm really concerned and confused about my feelings for my mother and father. I'm a male 17 year old with the typical teen hormones. But something really isn't right. My mother and father are really kind people, selfless, caring, and they stop at nothing to keep the mood high in the house. It's as if I were born in the perfect family, no joke. But for a while now, since I was 8-10 years old, a growing hatred grew for my parents. I never knew why, but every time I looked at their faces, I gagged. When I watched them chew, the only words that still come to mind is repulsive, sick, and disgusting. Norhing happened to cause this. All was well. Though at one point, my parents did split up, they got back together again, because they truly loved eachother.

But again, every time I looked at them, I felt like punching stuff, and became homocidal, I even almost killed their cat, glad I didn't. But I never took action, not even punching the ground, or my hands. And I still never do anything with this anger and hatred. I have always bottled it up inside and have NEVER let it out, or let it go. I learned that if I kept doing this, it would grow more and more intense, and that I would respond to even more of their actions. But I still hold it within me. I never let my hatred go. But on the outside, I'm a really happy person! And I make everyone around me happy as well, with all the smiles I give them.

But my smiles are beginning to fade, and my parents are starting to see who I really am. They are starting to see how I look at them, and are seeing how I really feel. And even worse, what was once just a bottled up hatred, these flood gates are about to break, and I can only hold so much more.

I've shut myself in my room, still fearing if I see them, I might throw up, or worse, I might even kill them or myself. I fear their whole existence, because they don't deserve the pain I could cause them. With these words you are reading, it really does sound like u care, but like I said, I hate them with a pure passion now. I often have fantasies of me ripping their guts out now and tearing apart their bodies to hang around the house and yard. I do not love them.

Now all I wish to know, is if this is even normal. I'm afraid and I reek of bloodlust. So I guess... This is the perfect site to ask this! xD Thank you for your time, and be in peace.
