incoming call centres are infinitely easier than outgoing. Apply for it and see how you go. As people have said its a good way to pay the bills, and gives you the chance to get out and meet people near(?) you. Working is the best social life =P I remember you've said you struggle at times to build friendships (i know I do too) and working in those kind of environments will help that. In a call centre you pretty much have to communicate with each other, asking each other for advice, liazing with management about various things etc
I used to practically crap myself when the phone went.... now I actually look forward to the phone ringing, and i've got a super confident phone voice, everyone says i sound like that even on personal calls ha ha
