Post-traumatic stress disorder is an anxiety disorder caused by trauma. Someone with PTSD will often relive the traumatic event through nightmares and flashbacks, and may experience feelings of isolation and shame. #understandingmentalillness
Having lost a young son & my dad, this is true with any loss. You relive it frequently, especially close to their passing. Our family entered a season of loss where we lost 6 close family members very suddenly (2 in auto crash, 2 heart attacks, 1 stroke, 1 bizarre infection that became septic over the weekend) all w/in 15 months & was difficult to process. A few months later, we lost 2 more close family members who had battled an illness. Only the grace of God can fill such void.
