Is it healthy to change who you truly are inside?

Okay, so whenever I go out I get a lot of attention, good and bad.
I mean, I don't even go around asking people, "Hey, you, watya think of the way I move?" And there they are trying to get under my skin with their nasty looks and vibes. I notice that a lot of these people are usually very beginner-looking people, like they have no goals work a 9-5 job, are only living to make money.
I get respect and good vibes from educated people, people who carry a complete different vibe, look ready, prepared, focused on something.

These others, are they simply haters?

I can take it, but sometimes it's too much.

I'm doing nothing wrong, and I notice that I fit well into young, hip, environments, like restaurants, the mall, especially where there are a lot of teenagers. And I like being around them. I feel that when I am around them I can take drama, laugh along, etc. Not take judgments seriously.

I guess it's a side I will always carry, 'cause I love to talk, etc. Nothing wrong with that, right?
But anyway, I notice that people may perceive me as conceited, and I am kinda beginning to get annoyed. I mean, I've heard so much to not care what anyone says, but it's beginning to get my last nerve. I feel it when someone is right behind, I'm minding my own business, and they're there hating. Ugh! I mean, no one asked for their opinion, and unless they have something nice to say, back off. I can be friendly, but just don't be ignorant.

Now today I was being nice, I was sending out my love, and I felt good, inside my body, as I sent out this love to the people around me. I've never felt like this before. But right now that I'm here I don't feel like myself, I don't feel like I've gotten that rush I usually get everyday. I actually have a freaking headache. Should I just go with the flow, not think about it too much?

I wanna be nice, and yes, just be free, spirited, 'cause I am, but at the end of the day, I don't want to feel like I am faking it.

I'm a Leo, btw.

Talk to me.
