Granted there are few things more important than confidence in the job interview. Its right up there with wear clean clothes and try not to reek of whiskey or green bud. How is someone who hires you going to have confidence in your work if you don't?
I've lost jobs in fields during economic downturns, I bet most people here have. Quite unlike my fathers generation, or most generations that went before us as a matter of fact, most of the people I know have done several very dispirit things in their lifetime. There are people who taught college or were medical doctors who now drive over the road trucking. There are people who drove big rigs who now teach college. So it goes.
So one job went away, the next one - which may not even be anywhere near what you've ever done, might be the one you really like.
TG people do get hired. Its hard. Its a real problem in the community, but some do. As for dressing like a hooker, buy different clothes. Hooker is fashion statement, not a manner of dressing.
And yeah, reach out and find help. I have trouble with the statement that you feel 'rejected' by the TG community, when I know many in here who would argue that there is no such thing in the first place. You can't be rejected by something that does not really exist. So, ya've meet some pretty mean, low-down, self-centered girls out there? Yup, there are plenty. I know more than one myself. But not all are that way.
I don't feel some sort of vibrant personal experience at every TG event I go to. Far from it. Mostly I feel like "oh ->-bleeped-<-, they are setting up the big paper deals and pulling out markers and they are about to start drawing org charts and deciding who is going to be chiefs and who get to be the tribe." Which is right about when Tekla skirts her little butt right on out of there. Discussions of theory, philosophy, sharing life stories - all that I like. Coming up with a way to accomplish something - I'm down with that. Debates about organization and administration - count me out. Dancing, now your talking. There are lots of worlds to the greater TG experience, lots of different people, but I don't think there is one UBER community, not at all.
In fact, the TG community just mirrors, as most communities do, the greater society where some people will like you, others will not, most won't care one way or the other. And where you like some, don't like others, and feel more or less indifferent toward the mass you don't know. I've made good TG friends, and I've met others who don't like me so much either. So it goes.
