This applies to so much. It’s almost always people who have never experienced anything truly hard, no matter if it’s the same category, who do the “omg, that’s so me” thing. Experience of that leads to empathy, sympathy and understanding that someone else’s struggles with something that has never been hard for you can be the main thing that makes their lives difficult.
That’s not an exclusive thing, of course, some people understand that even though they have never had issues on the same level, and some people have had stuff that’s affected them and their lives more bit still don’t get that. But my experience is that those are outlier more than the norm.
