This is just so devastating. Our hearts are breaking for comedian and Catastrophe star Rob Delaney on Feb. 9, after he announced the death of his sweet two-year-old son Henry in a tragic Facebook post.

"I have very sad news. My two and a half year year old son Henry has passed away," he began. "Henry had been diagnosed with a brain tumor in 2016, shortly after his first birthday, following persistent vomiting and weight loss. He had surgery to remove the tumor and further treatment through the early part of 2017. Then the cancer returned last autumn and he died in January."

Rob went on to describe Henry as "smart, funny, and mischievous," and admitted that his wife and other children are devastated. "We had so many wonderful adventures together, particularly after he'd moved home following fifteen months living in hospitals," Rob continued. "His tumor and surgery left him with significant physical disabilities, but he quickly learned sign language and developed his own method of getting from A to B shuffling on his beautiful little bum. His drive to live and to love and to connect was profound." Rob says that he would "go mad with grief" if it weren't for the love of his wife and sons. "I don't want to miss out on their beautiful lives. I'm greedy for more experiences with them," he said.

Rob, who is from Massachusetts but currently lives in London, thanked the NHS nurses and doctors, as well as the charity workers and home care people that helped them during the difficult illness, saying they "will be my heroes until the day I die. I am desperately sad right now, but I can say with authority that there is good in this world."

Rob is certainly a part of that good, as he used his family's tragedy as an opportunity to help others. His message goes on to request that fans donate to Rainbow Trust and Noah's Ark "in Henry's name or in the name of someone you love. Our family would be in much worse shape right now if it weren't for them. I would also urge you to take concrete and sustained action to support the NHS, however you can. Do not take it for granted."

Rob, his wife, and his two beautiful sons are so grateful for having Henry in their lives for two and a half amazing years. "Thank you, beautiful Henry, for spending as much time with us as you did. We miss you so much." Rest in peace, Henry.
