Hey, writerofthedead. It's the last day before sprink break, so this will be my last chance to return the favor, but I'm taking advantage of it.
This is overly dramatic and the prose is flowing with grammatical errors. You've already recieved help with that though, so i'll go on...
First off, to avoid melodrama and cliche, get to know your characters. This seems like the typical teenage cliche, and I see no individual spirit behind the character. Something you can do is "interview" him. Basically, ask your character interview questions and write down his responses. For the first time, it might be good to overemphasize his character in the interview and go back and prune later, but make sure he has attitude.
An example would be the father. If he knew his son halway decently, it would be completely unrealistic for him to be banging his girlfriend in front of him. That conflicts with what a father would do in the reader's mind, and you NEVER want a conflict in the readers mind. Instead, have dante accidentally 'walk in' on them during an intimate moment. Then again, that's been overdone so much...
You jump from thought to thought like a pinball. Slow down, a deadline isn't going to hit you like a mack truck. Really, the best way to work on pacing is to work on transitions. Use transition words like: "meanwhile, on the other hand, so, which meant, etc..." That will keep the reader on track at least.
The best way to learn to write is to read. The more you read, the more you will develop your "internal ear", which will help you a lot in writing. Just keep at it.
