Your attempt at shortening the word “didn’t” actually produced a word longer than “didn’t” itself. Congratulations.
If jorm4n is currently keeping you up, then the form of the verb to be used is “keeps” or “is keeping.” If, as expected, this action was performed in the past, the past tense of the verb must be used. For example, the sentence would read as such: “jorm4n kept meh [sic] up.”
