Can you recommend dramas where one of the leads (or both) have a mental illness? I’ve seen a few already but It's Okay, That's Love, Clean with Passion for Now, Hyde, Jeykll, Me, Kill Me Heal Me, etc.

  • It's Ok To Not Be Ok 
  • My Holo Love - The FL has propognosia due to traumatic incident
  • 30 but 17
  • Circle: The Connected World - it is all about PTSD
  • Beautiful Mind - The ML has Alexithymia but in the story it said that it he is a psychopath. The ML is a neurosurgeon. It is medical drama too.
  • I Remember You
  •  Mask - ML has anxiety and ocd
  •  Gap Dong 

Also:

  • My mister - depression
  • Healer - PTSD
  • Meloholic - dissociative identity disorder 
  • Time - depression
  • Scent of a woman - depression
  • Heart to Heart - sociophobia due to uncontrollable blushing
  • Just between lovers - post traumatic stress disorder and survivors guilt
  • What happened to Secretary Kim - night terrors
  • Mars - sociophobia 
  • I am not a robot
  • Introverted Boss
  • Flower Boy Next Door - 
  •  Sweet Dreams
  • Kingyo Club
  • I cannot hug you
  • Happy loner
  • Its ok thats love
  • oh my venus

Seen: It's Ok To Not Be Ok, My Holo Love, I cannot hug you, I am not a robot, Introverted Boss, It's Okay That's Love, and Oh My Venus...

You may also try

Good Doctor - a story of a doctor with developmental disability and and FL doctor that fall inlove with him despite his illness
Doctor John - an anesthesiologist doctor ML has CIPA illness (inability to feel pain)
Cheese in The Trap (kind of personality disorder on 2 main character)
Forest - PTSD on both ML and FL

I think there's more on movie than in a drama

Flower of Evil.  Will not describe more as it could include spoilers.

Me Too Flower

Be Melodramatic

Watching Flower of Evil now. Thanks for the recommendation!

Project S : Skate Our Souls -  superb acting from all leads, quite realistic, well not much romance but i would recommend it if you're searching for dramas relating to mental health.

It looks good regardless of the no romance tag. I’ll give it a try thanks!
