There's one quality that is always present in ADHDers who haven't yet or are just learning to cope with their symptoms.
Fragility.
Something negative happens, big or small, and it can cause us to collapse. Just break down.
This is true for EVERYONE at the start.
As we learn to cope, we become less fragile. We learn to become more resilient.
Learning to cope is a process.
Imagine trying to get better at talking to people. If you aren't able to handle RSD or self soothe, a single negative interaction can cause you to give up.
Personally, to get to a point where I was able to learn it, I had to first get better at managing my emotions.
Self soothe, so I don't spiral too hard.
Mindfulness, so I can more actively figure out what I'm feeling.
