Help with Casual-Conversational Skills

[drizzleRomanceGirl]

Will you please help me learn how to speak in a more friendly and casual manner? (This is more for real-life conversation than online chat, although either kind of help would be greatly appreciated. ) I have both autism spectrum disorder (ASD) and ADD, and although both are relatively minor, they have contributed to my roommates being uncomfortable near me in the past year in college. Today, I asked my roommate to tell me if she felt uncomfortable near me, and she told me that she was because I speak too quickly sometimes, have trouble reading when the person I'm speaking to is done with the conversation (and as a result, I tend to stand there for another ten seconds or so before leaving), and speak in a straightforward and "rule-based" manner. Thank you in advance!
