Kid Cudi Checks Into Rehab

Kid Cudi has checked himself into rehab for depression and suicidal thoughts.

The rapper entered Monday, saying he hasn't felt at peace for years and made the decision to get help for himself, his family, his best friend/daughter and his fans. Cudi continues, "I would've done something to myself. I simply am a damaged human swimming in a pool of emotions everyday of my life."

Cudi says his upcoming music will still be released as planned and he wanted to finish up all business before starting to focus on his recovery.

You'll remember ... Cudi lashed out at mentor Kanye West and Drake last month for not working with him and using others to write songs. 'Ye responded to the rapper at a recent show, telling him to "Respect the God!"

It's interesting -- it was announced in early September Cudi was to be replaced by Romeo on "Empire" -- but it's unclear if his depression played a part in that decision. We spoke with Romeo at LAX who said the move was strictly business and there were no hard feelings between the two.

KC finished his announcement with, "I really am sorry. Ill be back, stronger, better. Reborn. I feel like s***, I feel so ashamed. Im sorry."
