Mock interviews...there are probably different job resource business in the city that will do stuff like mock interviews and resume proofs and such, I wouldn't know the name of any of those places, but I know most of the cities I've lived in in Canada are littered with these kind of services, so a look through your phone book and what not might help. As for social anxiety, man, it sucks, I think I've found a few tricks though, laughing at yourself and being really silly and dramatic, comedian like gets you out of your shell and hey, remember, most people are anxious too. Try an improv or drama class if you can pop enough anti-anxiety meds or drink enough wine to get you out of the house
