How can I stay calm in this situation?

[Love]

There is this program for the "smart students" that I disagreed with online via Facebook with a teacher.
I am scared I might get suspended and/or even worse:expelled for disagreeing with somewhat harsh words. I need education to take care of my family since we are almost close to hitting the poor section.
The question is, can I get suspended and/or worse expelledwith somewhat destroying school reputation with
words via Facebook to the people that read my comment? Thanks for answering!

if this is in america they could press charges for slander, but i doubt they could suspend or expel you

It depends on school faculty how they react on comment you have given on facebook, i have done this before to my institute but they ignored and just warned me not to do it again. Don't worry they will just warn you. but i suggest you to apologize your head about your act.
