Help Can they send me back from school exchange if they find out I SH?

[MissWannaLive]

So long story short I am going to a school exchange in another country from Erasmus program. And even if we are all adults we still have teachers to supervisor us. Is it possible that IF they find out I SH they can send me back before the true date of coming back to the country? Is there anything like that in the program? Also do you have any tips how to cover cuts better? I really don't want to deal with a big mess when my head is already one that is too much for me.
