This seems like the should be obvious, but it’s not:
When someone is upset about something, validating and understanding their feelings isn’t going to necessarily make them suddenly forget why they’re angry. That person will still be upset, but validation helps them maintain some self-worth and optimism.
So often, when we talk about our mental health struggles, far too many people want to do the very opposite, by telling us that it’s all in our head, or if we got more exercise, time in nature, or practiced gratitude, we would be fine.
How about just acknowledging that struggling is valid, and that you understand. Turns out, that’s the thing we should be doing.
