Stress with family etc and school?

I currently have bad grades in school (9 class) and are missing very often. I promised my mother that I would go to school all week and so on until Wednesday and today I stayed home because I had something (I would not say here) where you can't go to school but now nobody believes me Somehow I'm no longer important to anyone here in the family. What to do? So of course it prove but that I can say today dad that and that. They still believe me vl ne punishment if I do not go to school 1 time no school 3 days ps4 gone (except I have a fever etc) anyway, anyone's advice to me? = (I cried before because I'm desperately squatting in front of my TV and doing my homework

I do not quite understand your text now, especially the end, but it should be told that if you promise someone something and then you do not keep it, eventually you no longer believe in any more.

Trust is quickly destroyed and takes forever to build.

You only understand half of it, but in and of itself you can simply explain to your parents why you can't go to school this week if you should miss a week for this reason?

Well, somehow a vicious circle… You have bad grades, so you do not go to school, you do not go to school, so you have bad grades… You promise to go to school, but do not go because of illness, you have no promise, so believe you are no longer… Usw

First of all, you have to make a decision and decide to break out of this vicious circle…

Well, you have bad marks, no buck and many diseases… So this school year is not successful… What can you do?

you continue the school year and stay seated…
You try to change something and go to school and try to get through
you change class already and go one class lower in the first half of the year, then you can make up for that and have good chances to make the other classes

Why do not you go to school? Are you scared? Before students, teachers, subjects?

Why are you so sick often? Are you a sissy that stays sneaky at home? Are you really sick then? Is it psychic? Do you react to your fears with illness?

Maybe a conversation with a therapist would make sense. On the other hand, you're just adolescent, you're not sick…

Again, the most important question is here, do you want to change something, then make the decision, not tomorrow, not next week, today and now!
