I don't work anymore but find myself more tired than ever can being bored cause fatigue? also suffer severe anxiety can that be a factor?

Psychotherapy: You list depression as a condition. Listlessness and fatigue are common symptoms of depression (sleep disturbance too). See a mental health professional if you haven't already. Psychotherapy (regular sessions, weekly or more) will help you understand and overcome your anxiety and depression. I hope you didn't stop working because of mental health issues-- that's a recipe for worse trouble.
