I do not know how big is the city where you are staying or how large is the Catholic community out there, but see what is there, find out if there are any prayer groups out there that you could join, I think this is what you really need, some friends with whom you could share your faith, your doubts and problems etc. The internet is good, but it is not the real thing. Plus, there is something about faith that if you share it with others, you just get more of it… the more you share, the more you grow sort of.-
As for retreats, try searching the internet and writing emails, who knows, maybe there are some programs for students etc (I think you are a student, right?). Well, here where I am staying I just attended a retreat two weeks back - the preacher was one Vincentian priest from India (if you ever get a chance to listen to them, I highly recommend - I have actually one mission on mp3 files, i do not know if i can send it somehow?) - well, all you had to do was sign up for it and give donation if you could… it was at my local Church.
