What is going on..?

Hey, there :)
It was pretty hard not to give up working today...You know, sometimes, you wake up and understand, that there is smth wrong...Is it inside or on the surface... you clean your teeth, eat sausiges,open the door, step out of your block, buy Virginia's tobaccos, walk across the street...you do everything that is common and easy, but realise, that you're doing it not as welll as always, smth is not OK... People are looking at you in a different way, "what, am I freaky or what?" I woke up, and caught myself on a feeling that I'm sick, but I was OK, may be I'm dangerously in love...I'm in love with the girl I even don't know...but this feeling poisons every moment and drops you in a spin of incorrect conclusions, actions and talks. It would be so great if I could jump out of my body and have a look on it with a different sight.Frankly speaking, I'm fed up with the road, that I cross right now, I do want to turn somewhere on a highway...OK...no, I would ruin alll this shit, and build everything for new...but I'm afraid...it's deep inside, you see it every time you come closer to a dicision...That's why I have a question, when and why do you feel a need to change...whatever it is? Do you tremble or what?
