Wrong to have a heart?

Someone recently told me that i was sensitive. I couldn't say anything to my defense coz I didnt know at that point if I was or not.Well, the fact that I'm making a blog out of what he said could probably hint that I am indeed sensitive. I said COULD.
Then again, what constitues being sensitive?If I laugh at every lame joke,does that make me sensitive? Does crying while watching Finding Nemo make me sensitive? What about getting pissed at people who are obviously in the wrong? Or letting my mind wander incessantly on dark, lonely nights? Or taking things seriously?
If I'm allowed to deduce from my observations, being sensitive means feeling the emotions. To the extreme. Letting your heart, not your mind do the rationalizing.
That said, I know I'm guilty as charged. But isn't being sensitive a good thing? I know with conviction that I'm not overtly sensitive to the point that I let everyone else's opinions and judgements bring me down. I still have my strong stands and opinions. I still know that Jim Carrey cracks the stupidest jokes. That Nemo was NOT JUST a fish. That some people deserve to be put in place.
Where am i going?
Anyway, what I'm saying is being 'sensitive' doesn't necessarily mean a bad thing. In fact, all the great people in the world were sensitive. If they weren't, they wouldn't be doing what they do. Ok, put the fame factor aside.
If you're sensitive bout others' feelings, it'll rub off on your own, naturally.
So if I go to great lengths to do a favour for someone, is it wrong for me to expect at least a fraction of the favour returned in times of need?
If I try to avoid uncomfortable situations by changing the subject or making a dumb joke to distract, is it wrong to feel hurt when that someone whose face I saved puts me down himself?
If I'm the one who's always giving, is it unjustified to feel that i'm being taken for granted?
If I'm honest, is it unreasonable to expect the other to have the decency of a reciprocation?
Being me, that's how I feel. Call me sensitive. Whatever...
But I don't show it. Somehow, there'll always be a smile. Only I know the real thing. And a few other close friends. Mai Yin said that even with that smile, that 'real thing' shows in my eyes. And I get angry sometimes, at the fact that what I show with my eyes are out of my control. That the damned eyes are in fact the windows of the soul. That I'm actually quite transparent.
The thing is, I've always appeared as the one who's got it together. Lotsa people think that nothing shakes me, nothing ruffles my feathers, that I just dont give a flying kite. I'm a hardy. I'm Thelma, I'm always armed with logic and good advice, that I'll always provide a listening ear. To a certain extent, it's all still true.
But I'm sick of being the strong one. I need a ear too.
Seriously though, if God were to appear in front of me and ask me to tell Him all thats weighing me down, guaranteeing a solution that's on my side, I have my doubts that I would.
For one, by baring my soul, I'd feel so naked. I'd be letting the weak me show. I dont want pity, I dont want someone to hold me when I cry. I'm NOT gonna appear a wimp. That's what my head keeps telling me. The truth is, a hug wouldn't hurt.
Then again, how's the hug gonna come when I dont let go of my pride and let the real feelings show?I guess being sensitive is okay, and so is being proud. But when there's a raging war between the two in you, that's when shit starts.....
