Hey Logan123987,
Don't be put off your dream.
For now, there will be no cadet programmes and unlikely to be any in the foreseeable.
Self funded training is the only real option which may sound impossible but it isn't.
I'd suggest starting with some trial flying lessons and if you can, ride along with some PPL holders, then gradually self fund yourself through that alongside a sensible career that will provide you with a solid income, which will be needed to pay for your training.
Consider university and a career which could take you down a path that would support future aviation learning, engineering is a great option.
If you're based in Scotland I'd happily take you on a flight.
