Rob Delaney has been a “bag of wet rubbish” since his son died 14 months ago

He said: “I’m a mess. My child died 14 months ago and I’m basically a bag of wet rubbish. I need a lot of help. It has been very hard. It comes in waves. I’ve learned to not control how the waves come. Right now I’m sad a lot.”

Rob, 42, has opened up on his loss several times, and says the reason he wants to speak out is because he wants to let other grieving parents know it’s “okay that they feel terrible”.

He added: “The reason I’m being honest with you and not trying to impress you, and make you think I’m cool or that I’m a tough guy, or maybe working through loss in an inspiring way, is that I have found that if a bereaved parent or bereaved sibling reads this, I want them to know that it’s okay that they feel terrible, sad, confused and so brutally humbled.

“I’ve been sad and angry and I am telling you that just in case somebody else who has suffered a terrible loss reads this - so they don’t feel like some a**hole from TV has it all together. I am a life-time work in progress.”

The actor - who had Henry with his wife Leah, with whom he also has two older sons, ages seven and six, and a baby boy born late last year - then praised charity Rainbow Trust for their work in supporting families with ill children, as he says Henry’s care worker was “like a paratrooper”.

Speaking to the Evening Standard newspaper whilst at the Rainbow Trust’s annual Trust In Fashion fundraiser, he said: “We were at Great Ormond Street Hospital for seven months, and then we were at our local hospital for seven months, and then we were home with Henry for seven months, and then he died. It would have been towards the end of our Great Ormond Street stay that we would have been hooked up with Rainbow Trust. The care worker assigned to us was a woman named Fiona who was just amazing, and remains so. She still comes and visits us sometimes.

“At that point we didn’t know Henry was going to die. We knew he was disabled by his tumour and his surgery. Fiona was like a paratrooper who just drops in and has the skill set to help people in unbelievable pain and fear.”
