The parents should of moved him to a different school, or considered some other alternatives, if after 20 attempts to improve the situation didn't work
Instead of just crossing their fingers and wish for good luck, and just repeatedly send their son back to the same negative environment...........
The parents need to take more accountability. Once again, after 20 failed attempts and yet they weren't proactive enough to take matters into their own hands to try changing the situation
By that point, its either changing schools, consider temporary home schooling, or maybe something online, or just find ways to take a short break. Because even if he never suicide, it still would of traumatized him for life, so either way its not a situation to be taken lightly
If you went to a restaurant, and they messed up your food over 20 times, or you took your car to a repair shop, and they messed up 20 times, I'm sure you wouldn't return even after just the 3rd time. But for some reason, they think its okay to neglect their own child's problems at school for over 20 times, and somehow still expected miracle to happen. I have no words left
