The poor thing has been really down since Eunhyuk & Donghae left.

I know that it's been said he's prone to depression. I'm not sure if that's true, but I've seen evidence of it in the past.

He tends to go through really low states ever so often, and that makes me sad.

If he really is struggling, then I feel for him. I know how it feels, trust me.

Poor thing looks tired, and it's not from too many schedules, because he hasn't had many lately.

He has dark circles under his eyes too. It either looks like he hasn't been sleeping well, or he's been crying. Hopefully, he's just been staying up all night playing LOL or something. Hopefully...,

I don't like seeing him suffer. It makes me feel awful. I hope something helps him smile soon. He was really attached to Eunhyuk and Donghae, and Siwon who's leaving soon, and I understand why he'd be upset about them leaving. I hope it's just that, and not something more serious, like a real mental illness. My poor baby..., Someone give him a hug!!!

He also wrote about being depressed on Instagram:

kimheenim: It’s been a while since I last went to China. Lately, I’m feeling depressed, but I think this schedule can make me happy. I feel excited, actually the reason I’m not on Weibo is bec. after my phone reset it can’t access Weibo. But, I heard you can view Instagram in China right?! I said right?!😃😃😃 #SorrySorry #KimHeechul #KimJungmo #OffToChinaToSing #Singing (cr)
