DEAR AMY: I was adopted as an infant and found my birth mom when I was in my 30s. She had gotten pregnant in high school and gave birth to me at 17. We lived in different parts of the country and after I found her, we saw each other once a year for over a decade until she died suddenly last year. After her death, her brothers and sisters, who I’d only met once before, started regularly calling, sending constant texts and inviting me to family holiday dinners and on family vacations. I don’t feel a connection to them, don’t consider them family, and find it very uncomfortable to be around them….
