I know how hard it is. I'm 13 so I obviously cant even apply for a workers permit until August, when I turn 14. I rely on a lot of help from my grandparents and parents and I know that they won't be around forever(my grandparents) so I'm trying to be as independent as I can. Babysitting is a GREAT idea.. that's what I'm going to start doing.
About the barn situation, I know that you're doing all you can. I mean people, don't get mad at her because the horse isnt out of there, as she has no choice but to keep her there until she buys her. Once you buy her though, she needs to be moved. Stalls should be cleaned about once a day. Even if you have to do it yourself. Who cares what Jay thinks? And I know you should respect your parents, but in that situation, you need to ignore them and do what's best for Duchess. That's what I would do. And if your stepdad knows ANYTHING he should be flipping out as much as you are! Just do what's best for her. I don't even go anywhere with my friends... I'm all about my horse.
