it's just because she can't be arsed to go to school.
Some of your posts are really difficult to read.
You recognise your own MH issues but won’t recognise your DDs much worse issues.
You need to change your mind set and realise just how crippling anxiety can be.
Imagine how you are feeling then times it by 10.
Getting mad at her or calling her a liar etc is not helping.
It’s not going to be an easy fix because anxiety doesn’t work by just doing it and getting over it.
My DD has anxiety and is physically sick and has ended up in hospital before over it.
Think of it as though you’re training for a marathon. It’s going to take time until she’s ready to go back to school FT without issues.
I would sit down and make a plan for September (if a trusted staff member can be there then even better).
Give her a lot of say in this plan.
Put this plan on the wall and get her to think of what rewards she can if she follows this plan.
We have students who start later/finish earlier or have free time in a calm room at the end of the day or during breaks etc.
If she does not go into school, she will be expected to complete her school work at home and there will be no phone or Wi-Fi until after the school day.
She needs to wake up every morning and get changed into her uniform and not take it off until home time (whether she goes in or not).
Getting her into the routine of getting up, dressed and doing school work will make the transition to actual school so much easier.
I have students who are allowed to stay home and stay in their PJs playing PlayStation all day and so of course they don’t want to come to school where they have to do actual work and follow rules.
If the walking to school is giving her too much anxiety then I’d look into make the biggest change there.
Can your work be flexible with your start times for a few weeks?
Can you see how much a taxi would be?
The mornings will always be the worst and I do think getting over this barrier will make it easier.
