I used to have a lot of trouble with maintaining eye contact with people, but for a different reason. I was born with crossed eyes, and as a kid, I was very, very self-concious about them. In any situation where they might be noticed-- in conversations, during picture-taking-- I’d get uncomfortable and want look away. I don’t think I ever maintained eye contact with anyone for longer than two seconds.
As I got older, I gained better control of my eye muscles. Now, it’s only when I’m tired or using my dominant eye that you can tell my eyes are screwy. But I didn’t outgrow my inability to look people in the eye for long. And it bugged me for the same reasons it bugs you: I didn’t want people to think I was uncomfortable, uninterested in what they were saying, or hiding anything.
Basically, I forced myself to look at people more when I talked to them. Whenever I felt like looking away (the habit was strongly ingrained by then, so it happened pretty much all the time), I’d tell myself that if I did, I’d seem uneasy, or like I was being dishonest, and so on. As apparent as it is to me when others look away when I talk to them, so must it be when I look away from others, I reasoned. Since I didn’t want to appear that way, I told myself, I had to maintain eye contact.
It was easier to follow those self-directives when I was talking (or doing something else :D) with people I really enjoyed being with, or if it was imperative that I do so (job interview, parents grilling me, etc.).
I also realized how tense I could become in the above situations. Years of self-consciousness about my eyes did that, I guess. I made myself relax. Of course, making yourself relax is much easier said than done, and not always possible if you dislike or are intimidated by the people around you, but I found a way to calm myself down, and it helped me a lot.
It’s going to take time to overcome it. I still find it a challenge to initiate and maintain eye contact with people. But you can do it. Wanting to change is the first step. Good luck, Ayesha.
