Aww, I loved uni too, have missed some of my friends too... Some of them have visited a few times, is that possible for you? Or to go visit them? (Could any of your friends maybe tell you of a job then? Maybe if you renew the friendship a bit, you'd hear of new opportunities...?)
Small towns can be 'not open' to newcomers, this is ludicrous though.. are you sure it was that bus?
You mentioned 99%'ers... Are there any 'equally well-off' people, and where do they hang out? (Or was that the drinking and drugs?) Do your parents have any 'family friends' (with kids approximately your age) or relatives you could hang out with (cousins and such)?
Is there an elderly librarian or someone who could be sympathetic and tell you more about the history of this place and your family and this place? (Maybe a relative, gradparent or aunt...)
In the tourism sector you probably need to be around on weekends and in the 'season', can you be free in 'off season' or at least on some days? Or take biz-related seminars elsewhere etc? Some places in big cities are 'lively' throughout the week, maybe you could take a day or a few off to go out elsewhere/visit friends etc?
The courses/workshops I've taken were in bigger towns/cities, and I met some nice people there...
Personally I'd try to find out what the deal is in that town, do they maybe/also just hate tourists and tourism industry or what... (it can be a sentiment in touristy places, I've noticed it) Have you talked to your family/parents about this, have they had similar experiences? Who do they hang out with? Are they part of any charities or community things you could be part of too? Do they support local shops/marketplace/local economy? Maybe things to consider... Also what is your place's policy? (An upscale hotel didn't let locals drink or dance there, so there was some unfriendly feelings there too..)
Take care girl and hope things get better!!
