I've forced myself over the years to make eye contact anyway, it's not pleasant but it does at least aid in reading people. The key is not to look to long, when your saying something directly to them look them in the eyes, but then blink and/or look away briefly. I find that taking a lot of these 'breaks' helps ease the discomfort, but it's still not something that I can keep up for long. If I know I'm going to have to go into a situation where I'll be expected to make eye contact, I do my best to clear time afterwords for recovery, and be sure I have gone through the situation in my head and thought out escapes (like the bathroom, or a fake private phone call for temporary relief and nausea, headaches, or mini-emergencies for leaving all together). I've also found it helpful to look in the areas just surrounding the eyes, which seems to work out ok a lot. For me its meeting people's gaze that upsets me, I could stare at eyes no problem if there wasn't a person who made me feel uncomfortable behind them! I hope this helps.
