He already knows

Do not force yourself to omit in your prayers the biggest thing actually in your heart right now, just because you're ashamed it's taking up that space. 

He already knows. The only difference now in what He knows is that he knows your're not talking to Him about it.

And yes of course it is valuable and important and good to not be presumptuous, we truly do need to be humble.

He still wants to talk to Him about that part too. Explain it. Even if it's not perfect; He's not going to misunderstand you. He already understands you. But us talking to Him about it anyway counts for something to Him anyway, Go ahead and explain everything to Him. 

He gives us good gifts in the meantime anyway. Of course we don't always get what we want in this system, but talking to Him about everything can only bring you closer to Him. 

It's true we ought not to be presumptuous. It's true we cannot have every relief we want now. Talking to him about everything, all of it, can only bring you closer to him.

Add - Another version:

You not talking to him about it doesn't make him not know, it just makes him also know that you're not talking to him about it.

You can talk to him about the shame you feel about it, too. Explain it as much as you want, talk about all of it, He won't misunderstand you. 

In fact, he already understands perfectly, Even if you don't tell him. 

But when you do talk to him about it, he also gets to know that you are going to him about it. And that matters to him, He wants you to go to him, and it can make his heart glad.
