The community is mourning 15-year-old WLHS student Wesley Welling, who was killed on Tuesday, outside the school.
"Given what the community of Westlake has already been through in the last 5 years in terms of significant losses, accidents and natural disasters, it would be normal and expected for some of that old grief to resurface as well," explained licensed marriage and family therapist and founder and President of Clearly Clinical, Elizabeth Irias, who is based in Thousand Oaks.
Irias told KCLU, everyone processes grief in different ways.
"Don't expect that you're doing to start by being in denial and then move into anger. That's for a different type of grief than what we are talking about here.
"It may take weeks if not months to really integrate and process what's happened," said Irias.
