Have you thought of talking to a psychotherapist at all? You may need to take some time out and get yourself into a better space. Exams can always wait.
Hallo meine junge Dame.
I took some german in University. It's not an easy language to learn.
So you're not good at school, what are you good at?
Have you ever had a tutor for any of the subjects you were having difficulties?
You might be depressed, but this does not mean a life sentence.
My suspicion is that you may have some neurotransmitter imbalance/deficiency and some post negative event stress, affecting your
daily life..
Lack of proper support is a concern.
I don't know how things exactly work in Manchester, as far as public resource availability goes, but I sense that you haven't been offered any substantial support to help you deal with your issues, whatever they are.
Are you open to receive some help, like counselling, tutoring etc.
Then throw the ball in " their" court, by expressing the very same things
you are mentioning in this post.
Don't consider this present situation as YOUR failure, it is the system's
and society's failure. But you have options.
Talk to your parent(s) or a teacher you trust you get along with to help you
pursue any options available.
It would be great if you can get help to alleviate your stress, have some assessment for any neurotransmitter deficiency, get tested for learning difficulties and get some tutoring to just pass your subjects.
And if you "think" you are depressed, a proper evaluation is necessary
in order to confirm it.
There are various non-drug approaches for depression or other mental issues, should you indeed need it.
Please keep me posted and let me know as things unfold, so I can give you more specific information.
Best wishes,
Niko
