I've been pushing people gently out of my life that make those harsh judgements about where I should be and when. Some of us deal with issues that many cannot understand. Am I less fulfilled or more disappointed? I don't think so.
I am self-employed part-time semi-skilled labor, working on an educational certificate for a technical job. I moved out at 18, 16 years ago, but have always had roommates. For me it came down to losing passion in college due to burn out from anxiety, depression, and a chronic pain condition. Realizing I don't need more in life anyway makes me smile.
Mental issues have definitely marred many relationships, but to be honest, failure has driven me to experience many things I wouldn't have tried if I had fulfilled the 'American Dream'. My own mother says I was an adult at seven, and have been regressing ever since!
My own guess is that most people on this forum are very socially skilled, attentive, and kind. It's everyone else who's crazy.
