even if you do manage to tunnel your connection out, you will still be using bandwidth and your isp will still be charging you for it.
you can try to set up a local web cache which will lower your usage some, Squid might help out. you can also try to set up tor with Squid, so your connection will look like:
browser -> squid -> tor network -> internet
which might help bandwidth usage and anonymity at the same time.
for non-web traffic you can try tunneling through tor directly.
however, maybe more people can help you if you try to explain your problem better, perhaps with better grammar and spelling.
The whole secret of existence is to have no fear. Never fear what will become of you, depend on no one. Only the moment you reject all help are you freed.
