I mad at my mom right now. How do I deal with it?

So i'm mad at her because she won't let me have a new cell. Trust me my cell is ****! The cammra sucks, I can't text, I can only call after 7, and the battery life sucks. And now she is going to disconnect my line and get herself a new one!! She says I don't use it. I don't use it because of the sucky battery life! Without my phone I lose all my freedoom I can't bike on my own, going to friends house, walking alone in the mall. I. Hate it. So I wanna know how can I deal with it. And I'm sorry it's so long and if my grammer and spelling. Thanks!! :) and please don't say I'm spoiled. I understand that kids in other countries have it worse then I do. I just wanna know how to deal with it.
