I am in state of sin and have sort of neurosis.when i pray i feel nothing but i want to change.can i stop sinning without consolations from prayer

By george i am not (?) but i have stupid tyrannical conscience that dictates me to change my life.Protestants are smarter and more succesful and that is truth

Yes i am catholi,but i really dont understand many things in catholicism.It is the most scary of all religions.What is the meaning of crosses and sufferings?Devil tortured padre pio for example continously and phisically.St Paul was tortured by devil too.Why?Protestantism is so much cheerful and happier.That is why protestant nations are the most successful in the world.

 
Sync, the above is basically what you have told us about yourself. So it seems that you are in a state of sin of which you are painfully aware, and you would like to get out of your own unhappy state but you cannot see how you will do it. Am I right?

You say you are Catholic but do not understand the Catholic religion. You find Catholicism scary, in fact the most scary of all religions.

There is only one way to escape from your own unhappy state , and that is to follow the way of the saints. Get yourself to the Confessional and  confess your sins to a holy and traditional priest. He will have the right words for you. He will tell you what you are to do to change your life. It will be a struggle. But you need to learn about the Catholic Faith which is the only genuine source of consolation for you. No matter how serious are your sins, God is waiting for you with open arms.

It is not without good reason that your "stupid tyrannical conscience that dictates me to change my life". There has been somebody who loves you who has been praying for you. Maybe you know who that person is and maybe you do not, but rest assured this is no accident.

Do not waste the opportunity but strike while the iron is hot. I am sure there are others here who will also be praying for you. Peace be with you!

 

Nadir is right, someone is praying for you.  

I will pray for you sync.  I've been following your posts.  Your pain and confusion is evident.  But let's look at the cup half full and build upon the base:

-You're honest with your thoughts, and that's the only way to root out error.
-When someone points out the error in a particular statement, you acknowledge your mistake.  That's humility, the cornerstone of holiness. "Thou art are not far from the Kingdom of God".  Mark 12:34
-You're struggling and searching, and you haven't given up. Why?  It seems you're being specially called by the Holy Ghost, because despite your fear of Catholicism and being drawn to protestantism, you are seeking truth and instinctively know it can only be found in the Faith. He has great plans for you, if you have the courage.

To your original post, we must define "happiness".  It is peace of soul. Only Catholics can have this great gift from the Father, dearly purchased by His Son.

The so called "happiness" of non Catholics (cults like protestants and muslims, or agnostics, atheists etc) is merely childish gratifications of the senses pertaining to worldly possessions or experiences.  Their 'churches' and lives are dysfunctional, often extremely so, since they lack the fullness of truth, only found in the Catholic Faith.  Even those who seem happy (I've been around prots all my life) have a cracking of the veneer, if you will - always searching and never quite satisfied.  

Please find a traditional priest, make an appointment with him.  Talk to him about some of your fundamental questions and ask him to direct you to materials that will help you to learn about the Faith.  He will know best what to advise you, after determining your state.

In the meantime, The Hound of Heaven reminds me of you.  First paragraph:

I fled Him, down the nights and down the days;
   I fled Him, down the arches of the years;
I fled Him, down the labyrinthine ways
   Of my own mind; and in the midst of tears
I hid from Him, and under running laughter.
             Up vistaed hopes I sped;
             And shot, precipitated,
Adown Titanic glooms of chasmed fears,
   From those strong Feet that followed, followed after.
             But with unhurrying chase,
             And unperturbèd pace,
     Deliberate speed, majestic instancy,
             They beat—and a Voice beat
             More instant than the Feet—
     'All things betray thee, who betrayest Me'.
