I'm not so sure that 'sliding scale' service exists in the UK (I'm assuming you're an American anon, given your use of 'dime'), because of the fact that NHS is available... I seem to recall looking into it last year, also, with no luck. But I'll try again (:

My mum really isn't in a financial position to help me right now - she shouldn't really even be helping me with rent but she does, so I can't ask her for more. But hopefully something affordable is out there.
