a depression dump is a person that cares about so many people and wants to help them, but when they ask for help people call them selfish.
person a: my cat died :(
person b: how can I help? wanna talk about it?
person a: awe thanks! byeeee
person b: hey my grandma died...
(things person a would say)
"oop-"
"oof"
"that sucks lol"
"stop dumping your issues on me"
person b: am I just your depression dump?
