I don't want to go back home
Is there a reason you don't want to go back home?
Yes, I have been suffocating at home
It's okay to want to be alone at times, but your family is expecting you to return.  They will worry about you if you stay away too long without letting them know why.
My family deserves it. They have been getting on my nerves. I'm sick of it. I'm staying here.
I know you're upset but I'm sure you're family is worried about you. I think you should at least give them a call.
