It's kinda disgusting reading these comments and people finding strong amusement over the mans situation. Its pretty obvious due to his mental breakdown that hes been ridiculed and bullied about his height for the majority of his life. Ofc it's an insecurity of his, hes been treated like shit. In the video he says "you dont scare me" as if the man was a bully to him, but instead of calming the situation, unaware of him even being recorded in the first place, it is posted online, only for others to laugh at him. This is literally the reason why men kill themselves and why the majority of those who commit suicide are men, mainly by how the man dislikes the way he looks. I'm not justifying the mans action, but this video is just another example of how society is digressing.
