I just need to get something off my chest.
I am listening. What do you need to talk about?
I feel that I do not belong here. I'm an outsider.
That's good that you can admit that you feel distant from others. This will start to relieve some of your pressure, because it's not a good idea to keep it all in.
I don't think that I belong anywhere. It just sucks. I'm out there like a tumbleweed.
Hey, I think you will find a lot of people feel the same way as you do. You should just take your time and find what you really like to do and pursue that. I think you might feel happy or content if you do this.
