How would i b able to o like get into professtional hollywood acting?

[SamiiiiiiiL]

i love acting and i love how much fun i have doing it. its the only thing that really gets me through the day (well that and dance). I really wanna get onto a t.v. show or do commercials because it's my one and only dream. i feel like my family sort of shoots me down and tells me i won't make it but i think i have what it take. i tried out for JRP last june and made it in, but we cant afford it. Is there anyway i can get into acting without going through and agency and is there anyway i can make it in that hard business without the money? please help it would be greatly appreciated and if everything were to work out i would be able o live my dream and show my family i can do it and do have what it takes.
