The lighter side of ADHD
Not to diminish the struggles of those with ADHD, but this is also a thing for neuronormative folks. Society simply tells us all to be brilliant in order to be useful for others. But the problem is that not everyone of us are the same and if we don't live up to expectations, we also end up disappointing ourselves. So, we try to keep up to please others, neglecting ourselves, and hence leading to burnout.
Just got stage 3 last month. Stage 2 sucks :(
Keep going and try to apply yourself to the ADHD projects as much as humanly possible, you will expand your attention on the things you get all attention deficity on, and can train to be absorb situations quickly and astutely, the more powerful your ADHD the stronger you can train yourself to absorb knowledge because your attention naturally grabs anything happening, also try not to get distracted by a TV every time one is on, so ignore the meaningless stuff, focus the ADHD on important things, and grow as a person using your "disability" as a tool for success. -you will be exhausted regularly if you are doing it right, that much processing has a cost-
