What are we?

What are we?
That question always troubles my mind!If we are only blood and flesh what would realy make us happy?I often encounter these awfull brakedowns where with no reason at all i find myself loosing its self-meaning and  the satisfaction that gates from things.And i wonder myself what brings these catastrofic-like situations into the reality??At that moment only one drug would make me happy, from nothing at all!!Are we only hormones and siquels of electrical sparks at our nerve-system?!A very depressed person takes medication and solves its problem in a second.I feel depressed and as soon as i taste a chocolate i feel a little better!
If we are only cells of replaceting dna as the famous poem says, then why should we contiue living a life in which we aren't feeling good, we aren't factioning well as organisms?!These are my questions the same time when really few people on earth consider themselves as happy!!Why can i get tha feeling?Why are most people satisfied by their miserable oldrinary lives??

So what are we the moment that we are unhappy??

A man winthout happiness looks like a bird without wings, he is doomed to die.What differs us from that man??Only a coctail of substances in our organism.That morden science says so.And that is something that is practically showed by drugs!!!Even though everytime i am in such a bad situation i can answer that question reasonably, so i let that to you...
