Car won't start!

[whateverjames]

yesterday i was sick, couldn't go to work, today my car won't start. when i turned the ignition everything was normal, and it started to crank over for a second and a half and just stopped, and all heard was a high pitched motor sound, i opened the hood and it sounded 'like' the fuel system when you turn the key over twice, but not start it. the high pitched sound got higher and higher so i grabbed the keys from the ignition hoping my car won't blow up or something. and the electric motor wouldn't stop running! i ran in the garage to get some tools to take off the battery wire to end the problem alltogether. when i put the wire back on, the electric motor, (starter i'm assuming) turns back on without the keys in the ignition! WTF two days missing work doesn't look good
should i just have it towed to the dealer or is there something i can do. i already called into work and their not too happy, that's been said and done, now i have to worry about fixing this by tomorrow. and my parents are out of town for the week, i have no car to drive. please help. thank you
