My turtle commit suicide

I don’t know what to fucking do. I’m so lost. I’ve had this turtle since i was five years old. I took care of him for 20 fucking years. 20 FUCKING YEARS. And this piece of shit decided that he didn’t want to live anymore. He loved being by the window looking at the outside world. Well, this idiot decided that he had enough and jump of the window. He broke his shell and started bleeding out. I don’t know what to do. His name was Hamilton. I miss him so much . I’m lost for words . He had everything. Fly high Hamilton
