I don't know if it's possible to embed Instagram posts (if so, Mods feel free to help), but DJ Carton posted a pic and asked followers to "Ask me a question".

Someone asked why he left Ohio State to which he replied:

"Last time I'm sayin sum bout this...but they ain't "have room for me".  I had no intentions of leaving...still love ohio and my boys gon get shi done"

I have no idea why he would have been asked to leave, but there's obviously some more to the story here than just him choosing to leave for 'mental health reasons'.
