I have lifelong trouble focusing and organizing , I get hyperfocused on some things but avoid other tasks, I sometimes speak out loud involuntarily, my mood shifts quickly depending on situations, I feel restless, sleep around 6 hours or wake sometimes, and my BMI is 15.
All of these could be signs of adhd, but none of these are definitive without more details.
