Psychological injuries are common in truck accidents, particularly in severe accidents. In some cases, an accident is so traumatic that, regardless of whether you witness it or you are involved in it, it could cause post-traumatic stress disorder (PTSD). You may also suffer anxiety and/or depression, especially if your injuries are long-term or permanent. Long-term injuries have a psychological effect on injured individuals because they may feel helpless, as if they are a burden, or because of financial stress due to the inability to work or a career change.
