feeling hopeless :/

I'm not sure really how to start this. I'm sixteen and I have been in an abusive family-- from what I remember it all started when I was nine. I've went through physical abuse, verbal abusive, and psychological abuse. Right now, I'm going through verbal + psychological abuse with threats of things turning physical. I tried to ask my mom if I could get a job yesterday, she scrunched her face up and had an attitude (or some type of sas) about it. Talking about my grades that are fine -- two a's, a few c's, and one D because of a bad score on a math test. My mom also said because I don't come outside of my room and "socialize" with people I don't have the privilege to have a job. All I said was ok, then she told me I could "get the f out of her room" if all I have to say is ok. So I did.. And slammed the door behind me. Then she said I could put my computer on the table that's by her room-- I think she knows I talk to my boyfriend on it. Then her and my stepdad called me back, and said "what the f is your problem" into response I just said we been over this before. She let out a sigh and rolled her eyes  and just said "girl". Then I said I don't like how I was talked to, and somehow she was appalled. "You act like I cussed you out, I didn't." and on and on. then asked if she did, I said "you didn't but I didn't like how you talked to me". My stepdad said "If you feel like you don't like how she's talking to you you can get the F out." So I did. I went to my friends house, then he wasn't home, So I went to my boyfriends house while he was at work. My mom was blowing up his phone asking for his address and if I'm there, he asked if everything was ok and what happened. My brother knows where my boyfriend stays and showed my stepdad the directions, and told me to come back home. I got in the car, on the drive back home.. silence. I went to my room, I hadn't eaten or showered and barely drank. Later that night I heard my stepdad justifying his actions and saying I actually should go because of me not "doing what they say" and "making it seem like I'm being mistreated".  he was talking to my sister, in which she agreed. (she's older, 20) he asked questions like "do you wanna keep going through that?" and he said he didn't kick me out, he gave me a choice and changed everything he said. "I told her if she didn't want to follow the rules she can go, so she went". Justification. again. Fast forward to the next day-- today, I overheard my mom talking to my sister again. "she wants to get a job just so she can plot and scheme on how to get out of the house and run away with her boyfriend I'm not allowing that to happen" my sister agreed more, and said my boyfriend was "covering for me" but he was at work and didn't know what was going on until afterwards. Anyways, any advice-- I'm heavily restricted-- no phone, no nothing really.
