Help finding jeans that fit?

I am 4'8" at age thirteen, so I am very short for my age. I have big hips, long(ish) legs, and big thighs. I am forced to wear kids' jeans, but 10's are too short, 12's are too long & far too tight in the hips & thighs, 14's are way, way too long, and 00's are too baggy, although they fit in the hips. I feel like I can never find any jeans to wear, and I honestly hate it. I also have size 5 feet, which means I either have to search & search for shoes, wear boy shoes, or wear kid shoes. I have no self-esteem, and these things don't help anything. I most likely can't afford to get my jeans 'fitted', either.
