If you saw the person get killed today, or witnessed violence, or suffered violence, chances are high you have been traumatized.
You may not make the best choices in this state. You may need to do your self care. You may need to step back.
Damage from this sort of shit is real but it doesn’t have to totally rule you. Your mental health is important. Slow down to take care.
If you feel totally frantic, urgent, adamant, you may really be the one who needs a time out for self care. Ask for help if you need it.
