Here's one more: 'Friend left, alone now.' Losing a friend can be really tough. You get used to having them around, sharing things with them, and when they're gone, you suddenly feel very lonely, as if there's a void in your life.
Think of tragedies like death or separation. Then condense it. Such as 'Mother gone. Empty world now.' You need to strip away all the extra details and get to the core of the sadness in a very concise way.
Use relationships. 'Family split, home broken.' When a family breaks apart, it often means the safe and warm place we call home is no longer the same. It can be due to divorce or other family issues, and it's a very sad situation.
