I really want a horse, please help!?

So I dream like every night, and day dream every day about owning a horse, When I am in my back yard i just think about how good a horse would look in there. But money is so tight that we just can't afford one, i get that. But I mean I can't think straight in school, or anywhere for that matter. I know i cant even loan one so that is out. I am at the barn at least 3 days a week but it never seems to be enough, when i get home i immediately go back to wanting and wishing. I just really want some advice on how to raise money, or fill my horsey cravings, just some kind of advice. Please dont give me an answer like " Well if your parents say no then you just cant have one, that's that" I know that. I just need some help. Any advice is helpful. Thanks
