Körprov no availability around stockholm

I have taken the exam in järfalla twice but failed both times. I was closer to passing last time so now I’m looking for a new slot for the test but can’t find almost anywhere around stockholm. The closest date I could find is in norrköping on Oct 10. I don’t know what to do as the process has been very stressful for me. Why don’t they have more availabilities? This is utter torture. Do you have any advice on finding availabilities? How was your experience? Thanks
