»Blurry«? Do you mean pixelated?
Photohop is a pixel oriented image editing program, so text will be represented by pixels on-screen and in file formats that do not support that kind of data.
But if you save a pdf you can maintain vector and font data (provided no faux styles are applied, …).
i only have photoshop and indesign
Then why don’t you use Indesign for type to begin with?
