I'm always too blasé and it kinda scares me.

Like, I have an I don't care attitude but it's too much.
I'm numb. And I don't if it's just the way I am or there's something wrong with me.
Even when it's something important, even when you tell me someone of your friends died, I still wouldn't care.
I have a test in 10 minutes and I didn't revise. Don't care.
You show me a picture of war and people dying. I won't feel a thing.
You tell me you hate me. I don't care
You tell me you love me. I won't care.
I can't even remember the last time I cried. I just...Don't do crying ?
Sometimes, I even have to fake emotions and reactions not to look weird. Like smile or laugh at something everyone finds funny, or faking being sad because someone died or is sick or suffering.
I just...Don't care.
Even the number of people I care about are like...Probably 6 people.
For exemple, I love my best friend, I spend all my time with her. But if something happened to her, I know I'll be faking safeness, or I will be more sad about me being alone, than about what happened to her.
Maybe I'm just too self centered, or arrogant or narcissistic...I don't know.
