emotions !!!

It might sound strage to people who know me, but fact is that I am an EMOTIONAL person. in fact, i was an emotional person from the time i rem feeling sad, when someone had scolded my sister in our childhood... but an equally shocking fact should be that, i will not express my emotions, no matter what.. i am bad at expressing them and i am equally bad at reacting to them... i had somehow got this notion etched in my mind, that expressing emotions to or for someone are actually a sign of weakness and hence shud be avoided. i hv, till now, by and large, been (or may be acted like) a person who is unfazed by any body's emotions. but in past few months or may be a yr or so, i have been thru such diverse emotions, which have compelled me to think about them. and why shudnt i be thinking about them, as it s a significant 'sense/feeling/trait' which distinguishes us from other living-beings.... I have always tried to understand wat my emotions mean.. and i shud admit that i am still not very clear about them..
i feel that "emotions" is a byproduct of ur growing age, which will take various forms at different stages of life... wen u are young, u are emotionally attached to ur parents, to ur siblings, to ur closest friends.... and as we keep celebrating our birthday, year after year, these emotions will undergo a gradual change, with or without our knowledge.
the 'restrict ur emotions to yourselves' has made such an un-breachable shell around me, that i am scared that if someone will ever come to know what my true emotions are!!!
