How to start my screenplay?

[CoolBird]

In the beginning of my screenplay, there is a homeless teenager (Luke) who ran away from his abusive parents and is now living on his own in his car. He works 6 days a week, does drugs, drinks, and makes all the wrong choices. Eventually a single mother and her little girl find him and take him in. That's the first part of my story.

I have written after this point but I have been avoiding that part because of these reasons:
A. I need a good job for the teen. One where I could possibly film for free.
B. I need a way for a single mother and her daughter to find him and want to take him in.
C. I want to display drug use and maybe drinking.

The beginning of my screenplay is the boy running away. Then it cuts to a few months later, and his car is on a parking lot. A train wakes him up at the same time every day. Then he goes to the gas station, gives himself a "sponge bath", changes clothes, gets a small and cheap breakfast, and then goes to work.

I just can't organize this chaos! Can someone please help? Thanks!

A & B are only problems because you don't know your own characters well enough.

I don't understand your question for C.

Well for A, I have ideas in mind, but nothing that can fit with B and also be cheap to film.

For C, I mean want to visually show the teenager drinking and/or smoking, but I can't think of a way to put this into the beginning of the movie. But I figured out C on my own.

In the beginning can you show The Teen kind of mirroring his parentally unproductive home life with partying? Then maybe he gets a hard knock lesson when His Mom’s Boyfriend steals The Teen’s drugs that The Teen was saving up and hoping to deal (In his mind and in his world the “right way”), but when the drugs come up missing, The Mom and Boyfriend claim they know nothing about it, that is until their more of a flop house than home gets raided by the cops and suddenly there are The Teen’s missing drugs and the Boyfriend trying to pin the bust on The Teen (while The Mom stands there revealed to have known all along) to save their own skin, so The Teen bails and strikes out on his own in a car he had fronted to him on the premise that he would deal off the drugs and pay for it (So more money conflict).

For a Job, maybe he works at a little run down two garage service station (Which would likely be pretty easy to find and film at) where he could:

A: Meet the Single Mom.
B: Drive-thru drug deal from and F the job up.
C: Possibly steal something and F the job up.
D: Have his car worked on if needed for the story.
E: Have his car like held captive when fired and/or can’t finish repaying the repair costs.

F: Have the original owner/seller of the car come looking for his money for the car, see it being held by the service station owner, but over all recognize the service station as an easy mark to rob – which goes homicidally bad and when the original car owner (now armed robber/killer) steals the car back as a getaway vehicle, it all points mistakenly to the Teen who seems to have motive and is wanted in connection with the bust at “home.”

G: The Single Mom (maybe despite being let down by the Teen somehow) can account for his whereabouts during the robbery gone fatal.

Just some thoughts.
