Twitter thread explains what happens when people with ADHD run out of medication.

Have you ever told a friend you're sick, only to have them respond that your particular illness "doesn't exist"? If you have ADHD, the answer is probably yes.

As another Twitter user notes, having ADHD often means seeming like a crappy friend.
