Steiner wrote: "I'm not allowed to have fun with others. It's like I've been chosen for a duty and I don't get to say no. Destined and chosen to be absolutely isolated from everyone."

Why? What is the objectively reason for this? Aren't you a person? So, there is no a rational reason for thinking like this.

Steiner, there have to be something that stop you for having contact with other people. For example, in my case is fear of being rejected and fear of being hurt.
So, why don't you try to think which are your reasons so you will be able to work on them and have the opportinity to have a better life?
