Dad, will everything be okay?

I'm so stressed about school, even though it is mostly small things, just the thought of an F on a test makes me scared, for no particular reason, which is very funny considering that studying is a slog that i just can't get through even when I try.

But it makes me wonder, does it even matter? Yeah, my mom will be mad, but is it this much of a reason to be seriously considering suicide?

Does it matter all that much?
