This happened some days ago, little background:  
Probably our school in the future is going to move our class, into another building of another school, and this is upsetting my friends, they say that if we would go in that school, we wouldn't do nothing and the general environment of that school is really bad.  


So it started when they talked in a group about it, and proposed to change school and go in another town, and I was really skeptical about this, like questioning everything of what they said and poiting every flaw about it, and possibly bad things.  
Then I exposed my fears and feeling about it (I had really bad years changing schools, which I encountered many bullies before), so I told them that I was afraid to encounter another bad classroom full of bullies, or maybe that school was even worse than our actual one.  


They started to laugh and questioning about my life in general with this fears and how i'm going to face life with this thoughts, so I got really angry, mostly because they were exaggerating, and I said to them that they are really shitty friends and left from the group.  


Now they are really angry and want apologies.  
AITA for saying that they are shitty friends?
