I see.
You know, when I'm feeling like this, I'm used to go to sleep, if I can, to finish this day, and to lose consciousness. If I stay awake, I just keep thinking, and thinking, but I'm not able to do anything, to solve the situation. It's like resetting my brain, to "switch myself off" from the current, from the... cycle.
Go dear... don't torturate Yourself in vain.
Have some nice dreams instead!
