The British rapper, singer, songwriter and actor has been a big advocate for people, mainly men, to open up if they're struggling with mental health issues.
Professor Green, real name Stephen Manderson, is also a sufferer of depression and anxiety, but has been very open about his battle.
The 33-year-old continued that call for openness in his latest post to Instagram, where he elaborates on his recent journey with the Black Dog. Posing shirtless he tells his fans he wants to get in shape and is committing to releasing new music within six months.
He says: "There's no after pic yet, this is the beginning of the journey. People are shlags and only post a view into their (often unrealistic) 'perfect world'. I've been a shlag to all things bad; a shlag to my depression, a shlag to drink, a shlag to the sesh, a shlag to not creating, a shlag to distracting myself from the one thing that truly makes me happy - music.
"I've been a shlag to EVERYTHING NEGATIVE.
"After surgery going wrong this year it slumped me, I look and feel like shit. If I still look like this in six months then I've failed. If there hasn't been a whole load of new music then I've failed.
"No one is going to sort me out for me, so I figured it's probably time I did it for myself. I can't have a dad bod without bloody having a kid first! And I can't leave music behind knowing I haven't peaked yet... the stuff I've started is the best yet - time to get it finished.
The post has received dozens of comments of support from fans, with one saying: "Go @professorgreen - love your honesty attitude and approach to life. I'm sure you'll smash your targets. So much respect for you."
As mentioned before, he's been brutally honest about his struggles as well as the broader topic of men being reluctant to talk about their feelings.
He wrote 'Lullaby' as a documentation of his mental health issues, with lyrics including: "Pretend shit doesn't get to me/And I suffer in silence when I'm hurting/A man's problems are his own/And it's my burden."
Earlier this year, he admitted to Sky News that his depression and anxiety were bubbling under the surface without him realising what was going on.
He says: "The world is a different place now. A woman's role has become more and more defined as you fought for it. As men, I don't think we've become, I don't think we're as emotionally developed as we should be.
"I don't think we've learnt to handle the stresses that we encounter in everyday life, nor the insecurities."
Professor Green revealed his dad and one of his uncles took their own lives within just two years of each other. In a Guardian piece he wrote: "Communication is a big problem with us men. We don't like to talk about our problems; we think it makes us look weak.
"Society likes to tell you that you have to be happy all the time, and it's easy to think that if you're not happy then there's something wrong with you. But happiness isn't permanent, it's not something you can feel all the time - and neither is sadness."
