I must say what I feel in this instance. I feel that you are a person who is seeking attention at this time in your life. I do not know, nor do I understand your situation/circumstances, but it appears to me that you require a great deal of attention right now. What I get out of your statement is that you do not feel that you have received adequate attention from God in order for you to continue to acknowledge His existence, or at least the existence and sacrifice of the Savior, Jesus.
I also see you asking others (us) to comment on what you are saying, and provide you with information that might cause you to consider your opinion.
Well, there are two options here from my perspective.
First: I could tell you to stop belittling the sacrifice that Jesus made for you, by stating that you no longer believe it is true. Then I could go into detail about how precious you are to God (and you are); so much so, that while humans were still sinning against Him, He still offered His all to save us.
I could tell you that if you turn your back on God now, He'll turn His back on you at the 2nd Coming of Christ, and the Final Judgement.
I could remind you that if you are telling the truth, and you were really a Christian, then you should know that to many, you are the only Christ they will ever see. In other words, the love of Jesus Christ, shining through you, because of your relationship with Him, may be the only time that some people you come in contact with, ever see that. I could tell you that you were the one that was supposed to lead them to Jesus, and when you go before God for the final judgement, he'll show you how many souls were lost because of your decision to walk away from Him.
In telling you all of these things, I would be explaining to you that your decision to leave Christianity, and abandon Jesus, affects many more persons than yourself.
But would you hear me? Would your heart be open to discussing these things? Would you feel the love of Christ in my words, as I say these things to you, and realize what it is you are giving away, and how many more will suffer because of your choice?
My other option is....
I could encourage you to explore the other belief systems available to you. I could perhaps suggest that I too once believed in Jesus Christ, but abandoned that notion for something much wiser (ie: placing faith in myself, instead, because after all, when have we ever steered ourselves wrong?)
In my instance this wouldn't be true, for I love God with all my heart and trust Him with all that I am. I call Jesus my Savior, and I know that nobody else, including myself, has ever earned 100% of my faith.
So there you have it.
Now which one did I choose? We both know, don't we?
