Cydia Crash! Please Help!!!

Donmega88

I have an iPhone 4S w/ 6.1 currently...every time I try and open Cydia, it immediately crashes. I have attempted to delete everything I have searched for thus far through iFile (I have the SSH Terminal, but literally have no clue how to operate it!) I do not currently have a computer at my home at the moment, my computer at work will not administer me to download anything as well...I really need help fixing this issue through my iPhone alone w/out a computer if it's possible. Any replies to this would be great, thx!
