Dr Ranj contemplated suicide before coming out as gay a decade ago.
The 40-year-old doctor - who frequently appears on This Morning - has revealed he considered taking his own life as he struggled to come to terms with his sexuality.
Speaking to the Sunday Mirror newspaper, the 40-year-old TV star shared: "I was truly broken. I felt like I was a really bad, horrible person just for being true to myself.
"In times like that, you have really dark thoughts and I did have times when I thought it would be easier not to be here."

Today I get to celebrate #love and #equality for all with my London LGBT+ friends, family & allies. This occasion means more and more every year & we must never be complacent, or forget why we have it. London #pride... I’m coming for ya! 🌈 @itv @itvpride @itvresponsibility @prideinlondon
Ranj - who left his wife as he gradually came to terms with being gay - said he was forced to "put myself together again" after coming out.
However, he's thrilled that his family have been so supportive of him.
He said: "I never thought my family would be as accepting as they are. [They are] the most loving and supportive people I know."

Meanwhile, Ranj previously admitted he doesn't like thinking about the moment he told his wife he was gay.
He confessed in an interview with Attitude magazine: "It was so hard and I still don't like thinking about it. I felt like my heart had been wrenched out of my chest.
"I was completely broken. It was the lowest point in my life. I can only imagine how hard it was for my wife, though - she didn't deserve any of that.
"I feel so incredibly sorry for what she had to go through."
