There are some very useful websites which can help you with advice on wellbeing. We recommend www.getselfhelp.co.uk where there are leaflets and worksheets to help you with range of problems. The leaflets on anxiety and depression are particularly good.
Good quality booklets and leaflets are also available from www.ntw.nhs.uk - the leaflets on depression and alcohol are ones we use reguarly but you will find many others to help.
