I too, once avoided eye contact all together. I was so ashamed of my face that I would look to the side of people or behind them. With the help of medication and therapy, I started getting my confidence back and looking people in the eye. The two go together hand in hand. And trust me once I say this, it will feel uncomfortable at first, but at the end of the day it is a necessary thing. People connect with eye contact, and even if you give ****ty eye contact, the very fact that you're making an effort is a wonderful thing and people WILL appreciate it. People are not scary, and you won't reveal too much about yourself if you give eye contact. It is necessary to give eye contact, a life is not really lived without it. I speak from experience. I spent 3 months not giving any eye contact, not even to my TWIN. My BLOOD. 99.9% the same DNA! It was awful. Now that's all we ever do.

The first step is looking at the face, not just the eyes, just looking at someones face, any part of it and then slowly fix your way back at the eyes.
Another tip is to look around once in a while, look at the person then look at your environment, if you're sitting in a park, look around, absorb your surroundings, it's very easy to get comfortable this way.
Good luck, I know you can make it through this.
