I know this might be slightly off-topic, but I also know that a lot of people with mental or other health problems also have financial difficulties - usually as a result of our totally punitive benefits system/underemployment, or having to get taxis because we can't cope with walking/public transport, etc etc etc.
I thought, therefore, i would highlight the role of Credit Unions. These are small, often local, not-for-profit banking services that provide ethical, community-orientated banking services to people the big banks don't want to touch with a barge pole. Their savings rates tend to be low - but so are their borrowing rates - far, far far better than the much-advertised "payday" loans and all the other "quick fix" money lenders who advertise so much on TV!
If you're on benefits/low income, and struggling, check out if there is a Credit Union for you - you can get more info on here:-
Good luck - hope this helps some people!
