Well what i learnt about him is he suffered childhood trauma abuse and he had stresses in later life financial and that he battled with depression. Shortly before he hanged himself he found out he had Parkinsons disease which could of led to him falling into more depressive state and eventually planning his own death. Hanging oneself must be a planned suicidal action not just spontaneous in the moment. He must of been aware of what was going to happen but was overwhelmed by depression. No one else knew but him. Thats why it was big shock. I didnt know he had Bipolar till i learnt that he committed suicide. Depression is often linked with stressful traumatic experiences which people can have bottled up inside them and is associated with alcohol and drug abuse and suicide.
