Mixed feelings

My family had never been the most supportive. Actually whether they know it or not they have caused me years of pain and self esteem issues. I've finally found something I'm good at, and I don't feel like involving them at all. Now it seems I have offended them by asking them not to attend any functions. Even their arguments against my feelings were only attacks on my character and reminders of my shortcomings. I feel that seeing them at a time when concentration and confidence are key that I might falter. I hate that I feel that way about my family, but I can't help it.
