I've been waiting for 2 years and a half to be able to attend to classes to get my motorcycle license... (the A1 category is available from 16 years old onwards) and I was promised that I'd be let to and that I could make it, but now when I'm facinng this, they don't let me anymore... I'm not asking them for money for the classes or for motorcycle and equipment, I just need their approval, written. Thwy don't trust me enough for this... How do I gain trust? How can I make it fast enough? Someone... Anybody... Please help... I'm losing my damn mind with this, I can't stand 2 more years of waiting in agony...

You could maybe ask to drive a car to move around.
It's very a very conventional and usually accepted thing to ask.
Because riding motorbikes is much more dangerous, and they could be scared you're a hothead who will ride himself to death.

And after you've safely driven your car, maybe they'll let you ride a bike. But it's not granted, be ready to face to fact you'll never ride a motorcycle before you're independent.

Anyway, you won't be impaired because you don't ride a bike.
If you're 16, focus on school, friends, art, on self-development,... You'll have to opportunity to ride in a few years, if it's not now.

I know but that was supposed to help me with school and getting sone money, I always have to go earlier from classes to get to the bus... If I had my motorcycle I could stay at all the classes and I also could get a job in the city... (the city is 50km away from me).

¯\_(ツ)_/¯ ask to drive a car, maybe

And don't get a job if it's not required, you already need to be serious at school. And enjoy friends and sport while you're not in college.

despair, despair, despair

repair that :)_

Well I would get a job since I'd need to have money for gas and rn I don't even have money to buy new boots, So I'm stcking up with the 4-5 y o ones.
