It is normal, I believe, for a human being to want her life to be about her relations with others. It is normal to not want to live alone. But we have to not let those relations become unhealthy. Often a person would rather some unhealthy relating compared to being overly alone. But those are not your only two alternatives.

There's a third way. But you have to seek it out. You are intelligent and caring. You have insight. There are worthy causes in your community that could put your talents to good use. It is awfully hard to get started. But it will be awfully hard to continue as you are.
