Conor McGregor is being heavily criticized on social media after he mocked actor PJ Gallagher’s mental health issues. 

The former UFC champion tweeted British sitcom star PJ Gallagher, mocking his struggles with mental illness. The Young Offenders actor has spoken recently about how he was admitted to a psychiatric hospital.

Today is one year exactly since I was admitted into St Pats with mental illness. This pic in @radionova100 was the last one taken before I went in. Absolutely torn up inside and scared out of my shite of what was gonna happen next. Today I’ve never felt better in my life. pic.twitter.com/Zqx8QCepfn

McGregor posted a tweet, which has been deleted now, tagging the actor describing him as a “sad pox of a thing”, and added that he was “crying in the paper bout depression”

The MMA star has been involved in many controversial arguments on Twitter, however this one has caused lots of backlash for the Irishman, and he’s been labelled as “nasty” and “disgusting” by fellow Twitter users.

Gallagher has received support from many after McGregor hit out at him. Including Irish footballing legend Paul McGrath.

Pj take no notice of bullies, you’re loved by everyone. Whatever you do don’t let him get the better of ya pal
