my life my dream

okay so the other day i got a call from this modeling place iv been wanting to go to for a while now, but couldnt because we didnt have the money. but i have a job now and i thought hey i could save up money and pay for it myself. i bring this up to my mom and she starts cursing me out. apparently that is selfish and stuipd and i should wast my mooney pursuing a dream of mine. she basically told me she knows i wouldnt make it, and that she dosent believe in me. which isnt that big of a surprise, shes never believed in me in anything other than grades, and she prob never will unless it benifits her. she told me not to waste my time and money on something this stupid. well who is she to tell me that my dreams are stupid, at least im trying to do something with my life that could help us both. but no she wants what she wants and thats that.
