I get why the corn was funny, it makes sense to me having depression. She was feeling really down, everything was pointless. She was on the floor at her lowest.

I get why the corn was funny, it makes sense to me having depression. She was feeling really down, everything was pointless. She was on the floor at her lowest. Then she saw a very concrete example of something just as pointless / sad. A corn under the fridge is going to be alone, forever (or at least until the fridge is moved). I think it probably felt like relief, she wasn’t alone. Someone understood. That’s what she had been missing throughout the blog post.
