Am I a failure?

Why did I fail all my subjects again? Got 35% for GP, 24% for Physics, 23% for Chemistry, 42% for Maths and 38% for Economics.
Moreover, I didn't perform well in my CCA.

What am I doing?
What have I been doing?
Or is it that there are things that I have not done?
I'll be finding myself these few days, I'm sorry if I had my mood swings on you.
