But anyway, to the point. It might be useful to include information on how the parent/carer/etc. can look after themselves whilst getting used to the fact that their loved one is self harming so that things don't get too much for them. Also, links to Counselling services, Samaritans, other useful groups in the UK, US, Australia and wherever else might be necessary.
