Identifying how the word is being used.

In following sentence, I have to determine what article can be there

_I need (a, an or no article) help making decision.

I can always look for the word in a dictionary.

Activities, efforts, or something that is given to someone or that is done for someone to make job easier : If the help in the sentence above is being used in this way, which seems to be, no article would be fine.

And it can't be used as the fact or state of being helped or useful. for a
context reason, I think. (I don't really know if that is grammatically wrong).

Finally, many dictionaries say that 'help' can mean : someone or something that makes it easier to do something.
And a little note saying : in singular was always there.

I have no clue what that means except that it will always be in singular form.
Examples seem to imply that it is usually used in this way when
the help is following the linking verb, describing subject.
But I can't be sure about that and this meaning might fit in the sentence
above.
The answer says there should be no article in the sentence.
I'm confused and can anyone help me?
