idk if this will suit you, but this one focuses on depression. i liked this because it showed how the healing process for the depressed isn't linear. it's pretty realistic. http://www.mangago.me/read-manga/cocoon_of_the_heart/
while this one focuses on the perspective of deaf people, how they see the world, etc. and how someone who desperately wishes to understand them does everything in his power to close the gap http://www.mangago.me/read-manga/hidamari_ga_kikoeru/
i dont if you've read this both but if you havent't, hope u enjoy them!

(Depression, self harm)
I found this not too long ago and really loved it. The chapters about developmental disorders start at chapter 5.

not looking for yaoi (shounen ai is okay). any manga recs that focuses on discussing developmental disorders realistically? like the struggles, information on it etc? (autism, down syndrome, asperger syndrome, adhd, dyslexia etc.)
something like

also looking for any mangas that focus on other disorders and disabilities like depression, deafness, mute, blindness, anxiety or loss of function on certain limbs etc.
