Nick Cannon is at his wit’s end over his anti-Semitic comments and his apology for them — he clearly feels he’s in a no-win situation, and now some fans are concerned about his well being.

“The Masked Singer” host let his frustrations out Thursday night, saying … “I hurt an entire community and it pained me to my core, I thought it couldn’t get any worse. Then I watched my own community turn on me and call me a sell-out for apologizing.”

He added … “Goodnight. Enjoy Earth.”

An hour later, he followed that up, tweeting … “Y’all can have this planet. I’m out!”

As you know … Nick came under fire for pushing anti-Jewish rhetoric on his “Cannon’s Class” podcast, which resulted in ViacomCBS dropping him. Instead of apologizing, he initially stuck to his guns and was defiant.

But he changed his tune after a discussion with Rabbi Abraham Cooper, and posted a lengthy apology for his “hurtful and divisive words.”

Nick’s frustration is clear from his Thursday night tweets — after initially getting backlash for the anti-Semitic remarks, he’s now getting backlash for apologizing. It’s interesting … you could read the apology backlash as a reflection of just how much anti-Semitism there is out there.

Some fans online took Nick’s tweets as a sign he might harm himself.

As we reported, Nick had a follow-up face-to-face meeting with Rabbi Cooper Thursday night, but the social media trolling is obviously weighing heavily on him.
