hiya
i second what lindyloo says about Cocaine Anonymous. i can tell that it is a completely non profit/self funded fellowship run by recovering addicts for addicts who need help. it is also completely confidential so only members in the meetings know what is being discussed. they helped my husband get off this drug and turn his life around. you can call them 24/7 and they will put you in touch with people who can and will help.
lindyloo is also wise to mention danman.. he is also in recovery and knows well from the inside the struggle you are facing.
from what you say you are surrounded by this drug and are using quite a bit. you must feel very, very physically and mentally unwell. you can come back from this though and i wish you all the very best.
good luck!
