Adhd is already taken much too lightly, it can be extremely debilitating to many people and impacts every aspect of their life. I’m tired of it being treated as a less serious or “less important” disorder. I’m tired of it being thrown under the bus. It can be just as debilitating and hard to live with as depression or autism.

I grew up thinking i was neurotypical until 9th grade, despite being diagnosed with adhd in first grade, because nobody treated it seriously as a disorder. All I’d known about it was “Hyper and draws in class uwu” until ealier this year, 10th grade, i found out about executive dysfunction, hyperfixations, memory problems.

I grew up thinking i was neurotypical, but that i was just lazy and st*pid, that something about me was broken because i couldnt remember things i had just been told, i was told that i just wasnt trying hard enough because i was a smart kid.

I thought i was messed up because of my hyperfixations, and i hated how “obsessed” i would get with my fandoms and how much my friends made fun of it because many of them were “cringey” (Mlp, hetalia, fnaf, and undertale to name a few)

Please stop treating adhd as nothing more than “hyperactive and easily distracted”. It’s fucked up.

Shoutout to autistics who are super literal

To autistics who are called gullible or too trusting

To autistics who get made fun of for literal interpretations

To autistics who are mocked for believing what people say

There’s nothing wrong with you for taking people at what they say. You’re not unintelligent or st*pid or d*mb for taking the literal meaning of people’s words.

You deserve to have people in your life who speak clearly to you in ways you can understand.

You are awesome. Don’t let the bullies get you down!

Dialogue Prompt Request #2 (Voltron, Shiro, sickfic)

NOTE: Here’s the second request fic! It ended up being…really long…again. I hope it’s not too long and that you can still enjoy it! It turned into a college au too?

Shiro woke just after six in the morning with every symptom he’d hoped would hold off until after finals. The thing that woke him was the coughing. The pain in his head, the congestion, and general achiness spreading from the center of his back followed as he tried in vain to stifle the paroxysms, burying his face in his pillow.

The last thing he wanted was to wake everyone else in the apartment. The rest of the group was asleep, except maybe for Hunk, who might have already left for an opening shift at the campus cafe.

Shiro sat up carefully, blinking hard against the dizziness threatening to send him toppling off his bed. He’d felt this coming yesterday when he got home around midnight after studying in the library. He’d ignored it while he finished his paper that was due for his first class today. He’d hoped, when he went to bed around two, that the scratchy throat and sniffling would be gone in the morning. Now that it was morning, he felt exponentially worse.
