no boot or recovery img nexus s

Hello I am Elly and I am a Noob. I brought a rooted Nexus S from ebay that was already rooted. I tried to flash cyanogen through clockwork but it actually deleted both the rom and the recovery. I am now stuck on the "fastboot screen." I do not have ADB access and the phone will not connect to the computer. Please help me....pretty please. Thank you

I think your best bet is to get advice from the guys at cyanogenmod.com

Sorry I can't be more helpful. :(
