How Would I Go About Talking With My Guardian?

I did drugs, I have been clean for 6 months (in 18 days:) ). I’m 16, I went to rehab and I’m in AA/NA/CA. I lived with my parents but they gave custody to my grandparents about two months ago so I moved to another state.
Last Wensday things got out of hand. I had fallen asleep without changing into my PJs (seriously.) and my grandma wanted me to make a bedtime list and I was like, thats dumb. And it turned into a fight and somehow my grandparents decided that I wasn’t taking my recovery seriously and toke away all phone rights and my myspace and gave me a bedtime and a wake up time. So I’ve been showing them that I’m taking my recovery seriously and talking about the meeting I go to and talk about my sponser, well…
I would like my phone back. My myspace would be nice, too.
I had already gotten all the contacts in my phone approved by my mom, and we set it up so I couldn’t send or get text after 10 (texas time, it was 11 in ohio, but here its 10), and I could call people after 11, but people could call me.
And it’s not that I just want to talk to my old friends, I’ve made some new friends from this state that are in recovery that I want to chill with.
But I’m seriously scared of asking her or talking to her about it, what could I do?
Also, they know I’m staying clean because I take random drug test.
