Welcome to SR Vox!
I don't know what part of the world you are, but the short answer to your question is yes, there are free Rehabs. You can call 1-800 662-HELP and they can re-route your call.
Why don't you post in the Newcomers To Recovery section here at SR and introduce yourself. You will likely get more responses to your question over there.
Good Luck with everything Vox and congratulations on your decision to get clean/sober
