ritalin or prozac. i don't know

i can't deal with doing almost anything for longer than ten minutes without completely losing interest and thinking of a million other things i would rather be doing and going halfway to insane if i have to do whatever it is i'm doing for one second longer.. i cannot focus on the task at hand, whether or not i like to do what i'm doing, it doesn't matter, i will distract myself with the first thing i can find, if necessary.
(yet i can get stuck in one thought for weeks and never find my way out.)

i can't stand to stay in one place for longer than an hour. i get up and leave, drive, go anywhere, nowhere, just drive, just to go be SOMEWHERE other than where i was..(and why does driving make everything better? because everything around me is constantly moving? it feels like i'm doing something, getting somewhere, accomplishing something, why?? because the world around me is changing?............
.........it feels like nothing else matters but what i am doing.. and maybe THAT'S something..)

i can't remember what i said, or even what it was about, ten seconds ago.
(yet i can remember with exact clarity, intensity and meaning, what you said five months ago.. two years ago..)

i can't pay attention to one thing for longer than ten minutes (i have five tabs open right now, and i keep coming back to this one when i get sick of the other ones.. ie. every two minutes) without wandering off in my mind or the world into who knows where that has nothing to do with anything..
(yet i can listen to the same song on repeat for days. weeks. and continue to pay total and complete attention to everything about it and seemingly never ever get bored.)

i can be raging pissed off in one moment, and five minutes later have nothing to say about it because i'm just not mad anymore.. be totally insanely happy, and the next minute have no recollection of how i could have possibly been that happy, 'cause that girl is gone.. know exactly what to do about something, and in the next moment have no idea how i could have possibly felt good about doing that, and have no desire whatsoever to do it.
(yet, there are things i just can't seem to ever let go.)

is it my world or the world around me that needs to change in order to not feel crazy.. (aren't they the same thing?..)

sigh..
