What does this text mean?

期待したくなくても、どっかで期待しんだなー モヤモヤまっくすだぜ、ほんとに

期待したくなくても - Even if not wanting to expect (or anticipate)

どっかで期待しんだな - expectation is there, somewhere

モヤモヤまっくすだぜ - it's cloudy (unclear) to the max

ほんとに - really (or seriously)

I generally agree with the other poster, but this モヤモヤ is more like "frustrating". It's a situation in which you're having trouble making decisions or cannot help being distracted or is having mixed emotions and such. In other words, in this case, the speaker is most likely trying not to think of something/someone but is not succeeding at all.

That's why you couldn't translate correctly, it is "spoken language".
期待したくなくても、どっかで期待し(て)んだなー モヤモヤまっくすだぜ、ほんとに

Reprint a sentence like a textbook for learnig Japanese beginners,
