Following up on my and Kenneth S.'s previous replies to you (https://www.wyzant.com/resources/answers/229251/please_help_me_guys_it_39_s_emergencyyyyyy), I'm guessing that huge in this context means 'extremely long' or 'excessively long', i.e., in the number of characters the message is composed of, and thus presenting a practical problem to type all of it in order to explain why you "couldn't."
And in the version of your sentence you gave in your previous question, you had the correct contraction couldn't instead of the non-standard variant of this that you present here. You also previously did not put a space between the last letter of message and the comma, which is in compliance with the rules of Standard Written English and unlike how you've given this punctuation here.
