I Heard That Repercussions Means Consequences or Something Similar

After my last post, the friend who'd said that "if you think about something hard enough then it would come true one day" responded to my post when we met the next day at school.

When she'd told me about it a while back, I'd looked at her and said, "..."
She was like, *nod, nod* "It's true, it'll definitely come true one day if you think it will!"
"..." I gave her a look that was between a glare and doubtful. "Like hell it will..."

But for now, since it's in my favour, I might as well think that it's true, so I posted it, my mind thinking in a joking mood.
Next day, she said this, "...I mean, you'd have to like, do something about it as well as think about it, for it to really happen..."
Me, "..."
"And it only works for something positive!"
Me, "..."
Oh, gosh, that pissed me.

My reaction-message: How the hell does that work? Only for something positive!? That's so contradicting! If "something will come true if you think it will" is true, then it would also stand the same for negative things! Because if you don't think that thinking about something negative will make it come true, then how will positive things!? If positive things can come true, then why can't negative things!? And there'd be no point for the "think something positive will come true and it will" rule if you didn't think that "think something negative will come true and it will" rule is true! Because then that means that you think that thinking about nothing will come true, however they're both about thinking about something!

Optimists makes no sense!!!!
Their reasoning is so contradicting!!
They're all just lying to themselves; they're that or awfully, mentally, psychologically blind, they're lying to themselves that the world is a great place. That only great things happen.
HELLLL!!!!!!!!!!!!!!!!!!!!!!!!!

I'm so pissed now; I'm so tempted to go grab that knife sitting in the kitchen and stab myself with it to throw a tantrum and have the pain make my head clear.
But no, instead I am now hitting the underside of the table with my hand continuously. One because the kitchen is too far away to walk and two because then that would cause troublesome consequences afterwards like cleaning up and bandaging, etc.

Okay, just then, I just hit the table intentionally with my knee, but now I sort of regret it since I sort of sent my laptop flying upwards... and my laptop is extremely precious to my orderly, repetitive everyday life. :/ Let's not kill it any further.
I'd need to find something else to thrash and destroy...

Okay, I just hit my forehead with a table calendar that is sitting on the table. It was too small and light; I could barely felt it. It made a lot of noise, though...

Hah... I want to see some blood and feel some sharp pain that will hopefully make me wake up, but I don't want to do it intentionally (because I can only hurt myself so much - I definitely won't intentionally stab myself...*sigh*)... what a pain in the butt 'wants' are. ==
