as a teacher, i tell you that its impossible that your teacher means it in the bad way, but as a still hurting student, i can fully empathize with you…. i went through a lot of hard times in the school system, so now on the other side of the desk, i try my utmost to truly care for each and every student to my maximum ability.
but, i would also tell you that there are many great teachers that really do care about their students… find one of those and explain to them how you feel. and if its not a teacher, it can be any role model that you trust.
and, perhaps, maybe there is something that you can change that will make it easier for you to feel differently about your teachers…
