This one I know is not as easy to do but for many can help a bit with the process. After the saddness and grief have set in for a while and you feel ready to look up, find a bit of light or create a brightside somehow. If a loved one has passed, consider making an event or a fund in their name to celebrate their life and your love for them. If tragedy has struck near you but isn't affecting you directly, reach out and do your best to lift those who need your support. Bring sweets, stay positive and try to find one good thing to focus on. It may be nice to find a project to pursue that will help memorialize the person or situation and will help keep the loved ones busy and preoccupied. Tragedy of any kind is so hard to handle but if we can look for the ray of light it can be just a touch easier. Join with others and find light.
