The prevalence of eating disorders has rocketed during the last year, particularly during periods of lockdown and especially among children and young people. If you or someone you care about needs help, please use the resources above. You don't need to struggle alone.

And in relation to Nikki Grahame, no psychologist should be offering analysis in the media about her, or wider judgement about her life, illness or death. If you want to know why, this thread explains https://twitter.com/DrPetra/status/1285245752684564481?s=20

You can help others affected by eating problems by sharing the first tweet in this thread as widely as possible. So many people are currently struggling but may not know sympathetic help is available. Make that your good deed for today (and use those services yourself if needed)
