Just something I've thought of.
Often churches, hospitals, surgeries and charities have counsellors that will help people free of charge. I've sen a few in the past and they've often been very helpful. It's a case of looking for what's available in your area such as on surgery noticeboards, asking the doctor, looking up charities such as MIND or the local hospital.
Charities sometimes also run befriending schemes so that a befriender can visit or take you out. There are also voluntary care groups that are being created around the country who also have different services that can help.
It's only a thought as I know how expensive private counsellors are and how hard it is to find the help we need.
