Does your teacher have any serious troubles over the class? In
my school, my teachers are not gaining enough respect, and my class
gets scolded a lot. If your class is like mine, it could be a main
factor to resignation. I know that you are sad over your teacher's
resignation. I hope you see her again.
Stress over family and school issues is a common thing in
school. Talk to your friends about your feelings, when you can talk
to them. Ask them about their opinions over your thoughts. Or, you
can also talk/write a letter to her, expressing your feelings
towards her. I hope that my note to you can help you.
