To be or not to be a mom and mentor? Please offer advice?

I can't help but be concerned about my future options about a family. My parents want me to have a traditional family, with a husband that is Vietnamese and Buddhist, with all the right status and of course have biological children. I told her outright that I didn't want a family and might as well live single my whole life if I had to follow her terms. I find that I would probably live alone and be child free but I am concerned about the obvious issues of being alone (dying alone, no one to take care of you etc). I even considered adopting Chinese, Korean, or other Vietnamese children if I remained single, but of course this would require a solid support system and my mom would rather have me stay single than adopting, saying she wouldn't even help me cause they aren't her grandchildren. I was a bit appalled and saddened by this declaration. If I meet Mr. Right (kinda doubt it) then fine, but if I don't, should I adopt if I am able to even if my mom doesn't agree with me? I am also concerned about any issues of adoption, behavior issues, no bond clicking, etc. Maybe that solitary life suits me after all... -.-'
