TEACHERS VS PUPILS

Okay I seriously don't get people. So assuming you have been school there's always that one teacher or more who will never stop being annoying. normally you try to not start something but your so tempted to tell the teacher about themselves. I know teachers don't  have to help you and mark your homework and help you improve most of the time some of them don't even care about you. I appreciate the ones who actually try to help but some teachers are just out of line.
 for example: theirs this teacher I have in my first year of secondary school someone most have been picking on me  tell her and she basically told me I shouldn't be a snitch since then I never liked her I obviously tried to stand up for myself and she told me that I should fight my own battles which is just rude.
Now I am in my third year of secondary school 3 weeks ago the week before the
Easter holidays my bag was literally full and my maths teacher had just given me some big test which was too big for my bag. so I have to carry it around I put the test next to me but I haven't touched it midway through the lesson she notices she told me to put it in my bag I say it cant fit she keeps on gelling me to do it and I told her it caught then she says do you want me to put it in your bag for you? I`m thinking did I ask you to do it for me I don't even  know where your hands have been so I say NO I put  the test on the ground she still saying put it away. SHE CAN CLEARLY SEE MY BAG IS FULL ANDS ITS A BIG BAG TOO. I put it on top my bag she`s still telling me to put it away. so I had to stuff it. all through the lesson she was picking on me none else everyone said she was and she knows it. I hadn't even written my name on the test. So from now on I`m not going to talk in her lesson unless its really important.

Hola guys ,  don't worry I haven't forgotten you guys.
I`ve got big news :
Last year the school set up program for students who are taking Spanish as a   GCSE I decide to take Spanish because a, it`s good to know how to speck a second langue and Spanish is popular
B, most universities or collage and even 6 form like their students to have a common second langue
even though I  don't like my teacher sometimes I still choose it. the school decided that it would be good if we have a Spanish exchange  so I  took part

 I thought it would be fun and help me be more interested in Spanish but everyone looks at the bad stuff  like what if they are a tramp, they steal something but how would they feel sleeping in a random strangers house so I doughty my exchange panther would be bad.
all I`m saying is everyone needs to focus on the optimistic side  all around me i feel negativity from others which I think needs to change.
 SO I WILL BE TELLING YOU ABOUT MY EXCHANGE PANTHERS VIST ADIOUS!!
