Please take into account: "As virtually anyone can publish anything they like on the web, it is important to critically appraise the information you retrieve. In particular you should be suspicious of "miracle cures" and sites which offer no independent evidence to substantiate claims".
We no longer list other organisation's details here because it is difficult to ensure all the information is up to date.
However, you will find some useful information at The Sheffield Mental Health Guide at www.sheffieldmentalhealth.org.uk/ and the Help Yourself website - Your guide to groups & organisations in Sheffield at www.sheffieldhelpyourself.org.uk/
