I like to be alone.. is that considered abnormal?

In my eyes this is not abnormal. I am a loner and have know this since I was 10 yrs old. I have raised my sons the best I can and am proud of them. I am at a p now. I want my peace. Am I being self centered? No. I am not. I am happy being alone. I am most accomplished when left alone. We are like artists without a canvas. Painting our own view of happiness. I am a Nomad. I walk alone.
