I am getting insecure day by day. I feel that if others come they will take away my friends and will become much better friends and I will be left out. This insecurity is happening because in my childhood days I lost my friends. My friend's left me for other people and I was left alone. I thought I had gotten over this insecurity but now when I am in a new city and trying to make friends, this feeling is coming back and I feel like a bad person if I don't ask my friend to hang out with other group of my friends. I don't know what to do..
