A 73-year-old woman was found dead with a plastic bag over her head, a coroner heard.
Lorna Plowright was discovered at her home in Oakdene, Wicken Green Village, on September 12.
The Lynn inquest on Monday heard Mrs Plowright had been caring for two relatives with dementia.
She had been worried about a solar panel contract one of these relatives had entered into and a recent arrest.
A post-mortem examination found Mrs Plowright’s blood alcohol reading to be 220mg. Coroner Jacqueline Lake recorded a narrative verdict stating Mrs Plowright had taken her own life but her intentions are unknown.
