What are we living for ?

The world is always changing, and we have to know how to deal with it otherwise we`ll be lost or have huge problems .
Sometimes, it`s better to face life than to run away leaving your problems behind hoping everything will get better or disappear, which is not the most conscious decision to make .
Life is very very very complex .No one knows anything about it, of course we know a little bit but since we were born everyone is teaching us how to think and how to act but how the hell can we be sure they know what they are talking without a valid proof ?
Who am I? What am I doing on earth ? Someday, will I be able to have friends from other plants ? Am I really in love or it`s just an illusion ? Do I really care about the others or it`s just crap ? Did someone make a brainwashing during my childhood ?
I have no idea how to answer to all of these questions, the only thing I am sure is that the society have always manipulated us and it`ll keep going like this. Do we really love dresses or it`s just because everyone thinks it`s beautiful and charming that it`s going to be one of the best clothes to wear ? And what about pink, is it only for girls and homossexuals? Only because someone said that ? These stereotypes are starting to kill me . Everyone should have the right to think by themselves and to act in the way they think is the best one without wondering how they are going to be accepted or excluded from our society .
Why do people have to criticise the others, arent they good enough to look before who they are and then to worry about the others` life ? It`s driving me crazy how we all know it and we keep ignoring it...
Why do people who cares about you keep lying to not hurt you and the ones who doesn`t even know you are corageous enough to tell on your face their opinion and sometimes the ones who loves you the most finish by disppointing you because deep inside they know we are going to forgive them because it was because they cared about you . HOW THE HELL CAN WE KNOW THESE THINGS ? I FINISH BY ADDING THAT LIFE IS A MYSTERY AND WE KNOW NOTHING ABOUT IT. SO LETS TRY TO FIGURE IT OUT AND MAKE SOMETHING REALLY GOOD OF IT .
