Overprotective mom?Sex?Im almost 15?10 points!!!!!!?

[ForeverYoung]

I turn 15 in October, and my mom is very overprotective. Last Janurary, I overdosed (it wasnt very serious) but she sent me to Vista Health (mental hospital) and I stayed there for 6 days. I was super pissed and so in Feburary, I snuck out to a party and almost ended up having sex with a 17 year old guy (ive known him FOREVER though) I told him that I wasnt ready so we didnt, but I felt really guilty and told my cousin about, and then 2 weeks ago she decided to tell my parents and the rest of my family. Now my older brothers and dad are PISSED and really upset with me, my mom took my to the doctor yesterday to get tested for STD's and started me on birth control && I have to get 4 shots I know that one of them was a gardisil shot..i cant remember the rest. but she grounded me and took away my ipod and phone. Im not allowed to talk to ANYONE except for her and my therapist.She pulled me out of public school, so now I have to do online schooling; she's using this new software called SafeEyes, so the only sites I can go to are Keystone (online school) & educational sites. EVERYTHING else is blocked, so I have no way of contact with anyone. Once im ungrounded she said she is going to monitor everything. my web history,chats, and she wants my facebook password and she has to be RIGHT by me whenever I use facebook/email/twitter, etc. Shes gonna read my texts, limit how much music and what music I listen to,what I watch on TV (she thinks Americas Next Top Model is "inappropriate" and "crude" and "vulgar" ) Im not allowed to go to sleepovers, or anywhere else unless she is right next to me the whole time.even on a date.she said its gonna be that way until im eighteen and out the house. Im seriously losing my social life, and now that im homeschooled, I have no way out of this hell hole but to run away, and Im seriously considering it.my parents are divorced, but my mom has full custody of me. everytime i try to talk to her about having more freedom (ive been a good kid ever since the whole sex thing) she says "im the adult and your the child!" and then leaves so i cant respond. i know she loves me, but im literally going insane. please help.

Thanks everyone<3
