When does Clyde in the book Fast Sam, Cool Clyde, and Stuff feel gloomy?

Clyde becomes very depressed after the death of his father. What makes him even more despondent is the fact that he never got the chance to tell his dad how much he loved and respected him. Clyde is quite a sensitive and thoughtful boy, someone who doesn't want to get involved in street-fighting or gangs, so it isn't surprising that he has a strong reaction to his father's death.
He feels heavy and tired all the time, weighed down by the burden of guilt and grief. Thankfully, Sam is on hand to offer much-needed support. He tells Clyde that he shouldn't feel guilty about not telling his dad how much he loved and respected him, but that the best thing he can do is to live his life in a way that would make his father proud. Among other things, that means getting an education, and at Sam's prompting, Clyde enrolls in a college preparation course.
