The actor hasn't updated any of his accounts since August 24, and he replied he won't be starting up again anytime soon. Lee Jong Suk said, "I felt that if I were to use social media when I feel unstable mentally, I would just end up saying nonsense... There are times when I'm about to write my thoughts without being aware of what I'm doing. I could just write in a personal diary, but people are like that."

He also commented, "I do think just updates on my life would be okay, but I will do so when I feel more stable... I'm continuing to do work though!"  

Hopefully, he gets back into the swing of things.
