Siblings Depression

I think both me and my brother suffer from mild depression. Yes, it's true. Here's the proof...

Case Study 1:
My brother wasn't able to do his maths homework last night. I think there was something he didn't understand and so, he got really frustrated that he tore the book. He crushed that torn page and just laid on the bed. Then he gave sudden kicks to the wall. He sat up, straightened that crushed page and tried doing that question again. Of course, he failed, got angry and threw the book on the floor and went to sleep.

Case Study 2:
Yesterday i felt very low. I laughed but still didn't make me feel good. I reached home and i still felt pretty shitty. Something's not right but i just don't know what it is...

Maybe it runs in the family...
