We don’t know if EP had hobbies other than on-line sleuthing but she doesn’t seem to have many ties to her local community - didn't go to church often, didn’t want her children to stay at a Christian schools. She didn’t work so didn’t have workmates.
Her main relationships in real life seemed to be with Simon and his family and when they separated she felt rejected and betrayed, perhaps more so than if she’d had other people and other activities in her life.
Of course, this is speculation and maybe after the defence presents their side we’ll learn of her multiple hobbies and many friends
