>>4 I agree to that.
But really. The way other people view you is different from how you view yourself.
I mean, there are otakus out there who look innocent to normal people, heck even act innocent but they are actually fujoshis!!! But it doesn't bother them because that's how they are.
If I were in your situation, even if I'm not, I would view myself as a person with a secret Identity. It would sound super cool!! XD Then, I would use that 'don't care' personality to stop bullies from hurting me and my classmates!
I would say, "I don't care if you insult me, really," then glare at them, "I won't care if I hurt you either. You're causing trouble that it's troublesome..."
*eyes of admiration* Well, that's how I'd be anyways if I had that kind of attitude.
But if you're still unsure of yourself, I'm pretty sure you're not a fraud. It's nice to see people helping others. But if you'd like to do it with sincere kindness, you should put your heart into the things you do to help people. Then, it would feel a lot more meaningful. :)
