Is it normal that i get certain urges/desires?
Is it normal for me to get the urge to kill someone? I mean, I've had these urges for awhile.
For instance; One day, I was minding my own business at school. When suddenly I started staring at a random person in the classroom, I don't know why, but I wanted to just leap out of my seat and strangle him to death. But, at the same time, I'm scared of doing it. I don't know who the person is, but I got the thought. But, I also seem to laugh when people die..I feel no remorse, or emotions to it. For (another) example: My grandma just passed away not too long ago, and when we went to the funeral, I had to step outside because I was laughing. I wasn't sad. I literally felt nothing.
I told my therapist about this, and she said I could go insane if I keep up these thoughts. But, how am I going to go insane, when I don't even like harming an animal of any sort?
All of this still happens to me now, so I'm starting to get scared to even leave my room.
Can someone please help me, or give me advice on what I should do?
(Please don't recommend more therapy, or meditation, because those don't help.)
