(i'm not asking for a diagnosis. i just want the heads up that i have something before/if i talk to a therapist)

i thought i had adhd, and then ptsd, and then anxiety, and now i'm here. i have several symptoms of the disorders i listed but not enough to count as a victim of one.  i'm energetic to the point that i struggle to focus (but i still can if i try so no adhd), i tense up whenever i'm on highways because of a car accident i was in a year ago (but i have no other symptoms of ptsd), and i get nervous over things that are dumb (but it isn't everything so no anxiety). i just don't know what's wrong with me so if someone could explain what's going on i'd be.. not happy but less stressed out
