Kylie Jenner received backlash when she casually described her indecisiveness as "bipolar" on Twitter on Wednesday.

After the Keeping Up With The Kardashians star wrote, "I miss my black hair, I'm so bipolar," she received a slew of comments from followers who were offended by the use of the term. Bipolar disorder is one of many forms of mentall illness.

@_juliannarae replied to Jenner's tweet with, "@KylieJenner that was 100% the dumbest and most ignorant use of the word bipolar," while @rrIovato  tweeted "@KylieJenner mental illnesses aren't adjectives."

Another one of her five milllion followers, @skeletonstyles responded,"kylie jenner with her "i'm bipolar" makes me sick" while another, @JakeYeahhh shared, "Kylie Jenner just tweeted 'I miss my black hair I'm so Bipolar:('. No, you're not 'so Bipolar', you're indecisive...and a moron."
