What should I do? I'm in a pretty hard situation.

I'm new to Reddit and this is something that's been on my mind for FOREVER. And I was wondering if anyone could help me. So ever since I was really little I've always wanted to do jumping, as I've gotten older though eventing is something I'm more interested in. Anyways I have 3 beautiful horses all of which are QHs, sounds great right? Yes and no, although I love my horses I live in a place with 2.5k population, a 2 hour drive to any barns with English riding available, all we really have is shitty old men who think they know what to do on a horse. None of my horses are trained in English riding either. Now let's clear some things real quick though, I know this is a strange situation and it sounds a little suspicious, i started riding when I was 8, but quit due to not being able to handle criticism. When I was around 10 my grandma bought 2 horses, which for some reason were just handed to me and pretty much told, teach yourself. After my great grandma died I also inherited her "grandkids" pony/QH mix. I have no clue what to do. Please help.
