Sorry to hear that. Just a couple of points that may help: First, the Tor access performance is not a linear function of your bandwidth, it's more of a "whichever is lowest" function between your bandwidth and that of the onion circuit that you're on at the time - which rotates regularly, and can also be changed manually. So, while you may notice slowness every now and then, it won't be consistently awfully worse than using the Internet bareback, and the benefits should outweigh the inconvenience.

And second, if there's a government firewall getting in the way, one of Tor's available pluggable transports ("bridges") should take care of that for you.
