I can cope with people being different to me. In the end, we are all different. What it really scares me are two scenarios: the one when a person can be putting a smile to you and you think you can open yourself to this person when this person is being fake with you. And, on the other hand, the advise my friend gives to me about smiling everyone and prettend nothing is bad. But, I know he tells me because he knows if I take risk they can affect me psychologically.
I remember he mentions " survive" several times.

Thank you for your replies. And I also wish you luck in your school. :-)
