Being ripped of your own identity

Someone once told me that i tend to be as sensitive as an egg's skin, and that i've got to toughen up.

Why are some people sensitive and others insensitive? How come some of us get so affected but life's circumstances that we react sometimes in real destructive manners…is it true that we can control it all in our head?

I believe that thinking and feeling are quite related but it takes lots of energy and focus and that we are not at all times set and ready to face situation with such ultimate tools, unless we are some yogi or are in a natural retreat which we don’t all have the luxury to benefit of.

So in short , we cant chose our moments of falling and sometimes unfortunately we face tough situations when we need to be at our best aspects and mental states, so how do we react, what to do in such situation? Can we lie? Or shall we try to be less perfectionists?

I guess such situations try to teach us something, since all life is a learning process , or so the wise shall see it (not that I am a wise person). So one should learn to simplify and make assumptions or else we can never finish our tasks in an imperfect world being imperfect human beings.

It does kill me to do that , but lets face it , we do not have any other option , of course other than running away and freaking out , which is not a very good one!

and obviously its never gonna be easier , and we are never gonna be required to stop thinking, choices will always have to be made , and the more we grow up , the harder the choices...why?????
