(this is just my experience with GAD+what I think would happen to me if I was in this situation, btw. Other people have other things and stuff c:)

Mundungus, being the cocky bastard he is, claimed that he could go a day with GAD, aka, generalized anxiety disorder. He even took it a step further and claimed he could go a day with your brain. That's what got him in this situation. God damn you and your ability to shove his words back into his face, and God damn your potion making abilities.

Yeah, you had managed to basically achieve the impossible just for something stupid he had said. Now he actually had to live a day with your brain. And you had to live a day with his. Thank God the Order was only meetings as of late, because the thought alone had his heart pounding. Jeez, is this what happened every time you needed to go out? How do you get anything done?

He did manage to get through the full day, though, without a single panic attack, despite the constant feeling of suffocation in his chest. Though, when night fell, hell began. He was laying in bed, as one does to fall asleep, when his brain, or your brain, technically, decided to start racing. The most prominent ones being,

You're going to die in your sleep

One of them are going to kill you

Huh. No wonder you never got any sleep at night. After what felt like ten minutes, but was really nearly half the night, of shifting around, he gently placed a hand in his chest, nearly wincing at that quickness.

This needed to be done already. He could not finish the night like this.

After building up the courage to get up, he left his room, eventually finding yours. Of course, you were still awake when he entered, and were sitting up on your bed. Closing the door behind him, he sighed, offering a small wave as you shot him a look.

He moved to sit on your bed, which got another dirty look. God, is this how you felt whenever he treated you like that?

“You need you to give me my.. functionality back.”

He started bluntly

“Now.”
