It's very possible this particular friend does have some ADHD or OCD issues. Given your history of emotional abuse this kind of individual is likely to be triggering for you. They can be charming and outgoing individuals, however, they have short attention spans and are not very good listeners and tend to get aggitated if you expect them to listen more than they can. Yes, and they do interupt and talk over and try to get you to shorten your attempts to get them to listen. It's hard because due to the fact that they DON'T really listen and even forget, you can form a habit of needing to repeat. They have very busy minds and do tend to take over and interupt and run the show. Given that you have social anxiety you probably at first liked that about this person because of how they can fill a conversation and take over which at first takes that pressure off of you.

A person like this is not going to want to listen to your emotional challenges, IT BORES them, they do not have that kind of patience. So, that can lead to your feeling your needs are being rejected. Not good for someone with a history of being emotionally neglected or abused. They are a DIFFERENT kind of problem solver. You are NEVER going to get them to sit with you and your emotional needs no matter how many times you try. They are simply not wired to be able to do that.

Maybe it's not so much your behavior you need to change, but your expectations.
