Why do good intentions go terribly wrong sometimes.?

So, every now and then things can just go wrong.
It didnt turn out to be what it suppose to be.
Life is full of unexpected moments.

I think i can handle this.
Emotionally or not.
It can be quite challenging.
But what is life w/o challenges.

Im upset , because i care.
If i didnt care,i wont be upset in the first place.
