"The last 3 years were the hardest of my life, I look back and still wonder how I survived," he continued in the heartfelt post. "I never quit although I wanted to thousands of times all day every day."

Of course, the last three years weren't just difficult because he was battling cancer. The father of two has also gone through a very public divorce from wife and costar Christina El Moussa, with reports of affairs and behind-the-scenes tension taking a toll on his psyche. The star recently confirmed that he briefly dated the family's 23-year-old nanny.

El Moussa ended his post by encouraging any of his fans that are struggling right now to fight through whatever they're fighting.

"For everyone struggling right now from any situation[,] remember [to] keep your head up and don't quit!" he wrote. "There is light at the end of the tunnel, stay strong! T"
