HELP!!! - 舊金山

sorry, I don't know how to type in Chinese through ibook,
so i can only use my poor English to seek your help...

last week, I came here to live my sister's home in Monterey.
the original planning was stay until August to learn English.
however, these days the relationship between me and my sister is terribly bad.
as a result, I want to come back Taiwan without her assist.

but the vital problem is I don't know how to get SFO airport..

I know there seems to have the airbus.
but I'm not sure if I can take that by myself.
I don't dare to talk with foreigners,
and I always couldn't understand what they talk..

so, I try to seek help here.
is there anyone willing to give me a ride?
sure, I will pay you,
but I hope you can tell me how much I should pay in advance.

or, I have thought another solve way.

if anyone know where I can live with little rent,
please tell me.
maybe I can try to live here alone,
because I'm worried about my parrents will be very angry
for my 1 week American trip.(I even haven't been to the Aquarium.)
I know this way is much more difficult than I thought, but I still try to..

please please please pleaseplease please please please please please please

give me a hand

:'(
