i got diagnosed when i was nearly 31 whole going back to school  my dad said i dont think you have adhd you are just like everyone else blah blah  was rough i didnt engage because its just hard to understand if you arent feeling the same  no two people are the same i would try to not take it personally - my dad is very supportive other than this one comment     keep your head up and try to manage your own symptoms if you cant find support within your family look for it outside your family such as on this sub
