I'm not sure if this is the right place for this.

I've been having violent thoughts from quite some time. Sometimes they tell me that killing my father who's snoring would be a great idea, other times I'm suddenly feeling angry on my friends and a desire to argue with them and even destroy them appears, I don't know what to do. I feel like Smeagol from The Lord Of The Rings films. The baddest part is that I almost picked the knife with the intention of killing my father - I don't want to hurt anyone. I'm afraid one day the thoughts will take control and god forbid what might happen.

What do to, what's wrong?
