You might want to try Cruse
http://www.cruse.org.uk/ another charity that offers counselling (either over the phone or face-to-face).
Grief counselling is something most qualified Counsellors can work with though so you can just search for one locally through the BACP website:
www.itsgoodtotalk.or.uk
Also try UKCP or Counselling Directory if no one appeals to you on there.
It might cost a bit more than a charity but you can choose a time/location to suit you and also have more of a choice of therapists.
Definitely give it a go though as it can be really helpful.
Please PM me if you want any more info. I am a Counsellor and know quite a few great people working in the NV area.
