Are you happy??????

This is the question one of my old college friends asked me yesterday.I am working with a very good company,i m more than satisfied with my work and work enviornment.My family is happy,I have no monetory problems,I have almost all the physical comforts i need at this age.
But frankly speaking i kept thinking atleast for a minute,and finally i managed with ,a mere "well yes......i think so."
This was not the truth.Because still I am skeptical as hell abou this.An honest answer would have been.."I dont know.".
But didnt dare say so.
So now I am forced to think "why the hell am I not sure of being happy?"
I could not have been thought of a better job than this atleast at this period of my life.
I have full family support.No love affairs or nothing foolish of the kind is troubling me.
then why??????????
I really dont know.
During my college days,i always used to think,one day i will have a job.i will have my own money.
I will be independent,free to come home at any time,daily i will eat something new,Monday Chinese,
Tuesday Muglai,wednesday Tandoori. and all...
I wilol be able to booze every weekend,have as many ciggetes as i wish during the day.
I have all of this now.But this no more feels like as it used to be in dreams.
why so????????????

I am afraid to tell this to God.as I think he will say....
"Dont come to me son.Your desires are infinite,once they are fulfilled you get new ones.I have more important issues than your filthy desires to take care of."
I just want to ask all you guys there.Is this the case with you?
I dont know I am saying all this ,but this is what i felt like saying.
Ending it abruptly.
