There are ways people can help the victims and families of the Marjory Stoneman Douglas High shooting, besides grief counseling services:
Donate to victims' funds: The Broward Education Foundation created a GoFundMe campaign to provide financial relief to the families of the victims. Additionally, individual campaigns have been started for many of the victims, survivors and their families. GoFundMe is working closely with these campaigns to make sure that all the money raised goes to the beneficiaries.
Donate blood: The Florida-based donation center, OneBlood, is asking for people to donate blood. It announced via Twitter that there is a need to replenish O-negative blood supply. You can find OneBlood locations on their website here.
