I actually purposefully stepped on my glasses once. It was one of the worst days of my life, that I almost never talk about. I was depressed anxious and desperate to escape my life so without any thought or planning I ran out my house. Somewhere along the way my brain through it would be a brilliant idea of crush my glasses to pieces. Lets just say that by the end of that night i ended up in the hospital and i learnt what shame truly is.
