I'm not in my comfort zone when I talk to people
Why does talking to others take you out of your comfort zone?
When asked something, I don't feel like I'm in a position to talk to them.
We all don't feel like talking to others at times, but if you find this is impacting you negatively, you should work on making yourself more comfortable. Try talking to people in certain situations and be confident, overtime you will be able to socialize more easily.
I still don't know how I can be more comfortable around them.
If you feel like you can't socialize with people because you're uncomfortable, then you may have social anxiety. It would help you if you spoke with a mental health professional, as they could give you better advice about how to relax in social situations.
