I'm staying away from friends, family, strangers, people at school. I just want to be alone.
Are you alright? Is there a reason that you are so isolated right now?
Yes. I'm taking a break from all people.
Taking a break from people is completely normal. Everyone needs to have a little bit of alone time but don't isolate yourself too long. Isolating yourself would cause people to worry about you and you may start to feel lonely because of it.
I don't care. I am doing exactly what I want.
If you want some time to yourself, that's perfectly fine! You really do need to be careful though because going without social contact for too long is bad for your mental health. Relationships are an important part of living a fulfilling life.
