Hi there,
Been following this post closely as I myself have been in a similar boat (not drugs, but financially close to ruin). It is a horrible feeling and you feel everything possible is going wrong around you.
Some close friends of mine here in Costa Rica have been through rehab and come out trumps. It takes a while to completely recover but it is well worth it. You need to do an intervention as no one would admit that they need rehab till they loose the last thing in their life and that is their family and friends. During these stages you basically need to sit the person down and tell them it is rehab or they are in the chance of loosing their friends and family. Experts from NA will assist in this.
For the money issue I will see what I can put together and send something over. Wont be much but I am sure every little helps… post your moneybookers email if you have one.
Sorry I can not be of more help to you.
