That is actually a very smart question and a good one. No there is no reason at all that they would be informed unless you and your parents decided to tell them.

As far as what they would think of you if you didn't tell them....that is a tough one. Maybe you do the best you can and they think what they think. Maybe you get help and feel better and your grades go up and it isn't an issue.

What is really important is your personal health and not what your teachers think. What matters is what you think. I do not know what grade you are in but you will have lots of teachers, some you like and trust and some you hate.

My daughter really struggled in High School. She was lazy and didn't care. (depressed). She didn't graduate with her peers. She went to adult school and got her diploma. She was so so proud to get that diploma. She earned it. She is almost 21 and got a 3.5 last semester in college. She had a really hard time as a teen and me and her mom helped her as much as we could. She seems to have come out on the other side in pretty good shape. Her teachers came and went and next semester she will have more teachers.

Lots of people will come in and out of your life. Latch on to the ones that can help you and don't worry about what the others think.
