Whatever the reason, my advice stays the same. Remove expectations and take care of yourself. If you keep expecting something you will keep getting disappointed. Find someone else who will listen and keep your distance from your mom and sis. You don't have to feel lonely because others are rude and inconsiderate. And I still don't think that sounds like ADHD. Like I said I'm married to an ADHD man and he's not rude like that. Your mom and sis simply sound rude, self-absorbed, and clueless. There's no DSM for that. Save yourself and go find someone who cares to listen to you and, I'll say it again, throw your expectations out the door. They will make you crazy.
