i would like to use limewire or any software that is related to that but evertime i try to connect it wont let me because of the firewalls of the school...is there any way around it? or am i pretty much screwed?

Try Phex & see if that can connect.
The problem might not only be the firewalls but special filters to prevent p2p software being used at your school. That practice is becoming common place at many schools.
