Ignorance

PTSD is integrated into Mrs Dalloway through Septimus. He is a World War I veteran who lost his best friend in combat.  Septimus has survivor's guilt afterwards and feels like he should die like the rest of his comrades. His worried wife Rezia takes him to a doctor who gives Septimus advice in an extremely insensitive way. He acts like Septimus is an object and talks to Rezia instead of directly addressing Septimus. Septimus grows to hate the doctor and in his final moments screams "I give it you!" to Dr Wilson as he leaps off a building. The doctor could've successfully helped Septimus if he had shown a little compassion or sympathy.  Dr Wilson does not understand the reality of war.  Only people who have been in combat knows what it's like being shot at and shoot back to essentially kill a human equal. In conclusion the doctor did not determine Septimus' condition and approached Septimus the wrong way, ultimately worsening his intent to suicide. Dr Wilson represents those who judge others before getting to know them.
