Being on edge, being anxious... that was normal for me. My "baseline" is just high anxiety. I've gotten pretty good at avoiding panic attacks but sometimes they are unavoidable. I try not to let it be so obvious that I'm anxious all the time. People will try to accomdate me or make me feel better, which usually just leads to making me even more anxious. I haven't had a relationship in a long time because of how I am. It's hard to meet new people, form new relationships, or even begin to explain to someone why I am the way that I am. I've heard, "Just relax", "There's no reason to be nervous" and more too many times; so I avoid it instead. But for whatever reason this guy is showing interest in me despite the fact that I haven't had one honest conversation with him and am, well, me... I don't know why he's sticking around me but I don't have any particular inclination to find out.
