Idk what this is but...

so since i was little i always had a hard time focusing, remembering things, and being way too hyper. and also since i was little i was always a little socially awkward unless i was really friends with you and i always got anxious a lot. but now since i’ve grown up i’ve had the same problems but i always feel like i’m happy but after i’m done smiling i feel sad. ya know? idk, but my dad has ADD so my focusing problem and hyperactivity could be that, but i’m just always very confused about my feelings.
