Utter Disappointment, the uselessness of mournful behaviour

I do suppose that even after receiving these terrible marks there is no point in being so low in spirit. When I reflect on how I have been studying for most of this semester, I know I have slacked off to a great extent. Not only have I failed to reach my expectations but also I've put forth an obstacle for myself...one that only I can overcome. I am not really sure why I have been very irresponsible in my studies. Being in third year now, I guess it's because I just want to be over and done with school.
I shouldn't give up now. That would be pointless. Yet, I can't help but feel so miserable.

I am very happy and very much in love :3

When you make a promise

...they sometimes fall apart and break into millions of pieces. Then you wonder...where did it go?
I've made so many promises. But I want to renew this one in particular. To trust in God.

Trust in the LORD with all your heart,
and do not lean on your own understanding.
In all your ways acknowledge him,
and he will make straight your paths.
Proverbs 3:5-6
