Hi @mubashara ! This is a very sad story, and it's heartbreaking to hear about your classmate's heart attack. May Allah grant her forgiveness and make their hereafter easy. (Aameen)

As I understand, sometimes situations arise where a person cannot find a way out of their troubles despite sharing their problems with others.

In reality, they get trapped in a whirlpool with no solution. And then, they leave this world with the same tension. We should try our best to listen to someone's problems, understand them, and make every possible effort to solve them. Because time once passed cannot come back, only memories remain. And words remain.
