"Family of Choice"
Paul is exactly right. You do have a "family" here.
You know why my mom doesn't have the same gut-wrenching power over me anymore? Because I have intentionally created my own "family of choice." I have women who are like mothers to me. I have men who are like fathers to me. I've adopted cousins, sisters, brothers, aunts & uncles... people whom I love deeply and are always there for me... and for whom I can always be there as well.
You have the power to do the same, my friend.
