I’m just curious how many people have taken out a loan to buy a horse, pay a stud fee, buy a saddle etc. this is just curiosity.

That's a big problem before I started working on my habits. You have to learn how to manage your finances and this is a lot of work and that is really very important!
Because of that I started learning and read a huge amount of materials, I ever wrote a blog post on how to write an economics paper.
I hope that everything gonna be great and you will find a way to resolve your problems! Good luck
