adhd evaluation?

hi, im a 16 year old girl and have been previously diagnosed w/ social anxiety and also just general depressed mood. ive always felt like my therapist was missing something but i couldn't describe it however the more i researched adhd the more i began to speculate that was it. my whole life ive been extremely fidgety, constantly moving around, when im not socially anxious im talking super fast and switching topic to topic very quickly, im also extremely innatentive. at school i physically cannot pay attention to anything unless im really interested yet somehow i manage to fake it and get good grades? i switch from task to task frequently, avoid chores as much as i can as well. im unsure how much these truly affect my life as of now but i can tell the second school and such stop coming easily to me i am absoloutely screwed and will not be able to do anything. i also read about rejection sensitive dysphoria and i feel like it explained my entire life. im currently seeking evaluation for adhd but should i even bother? does everyone feel like this and am i just overreacting?
