Hey there sweetie <3
I'm so sorry for everything that happened in your life so far, I can't say that I know how you feel, but I know that you're hurting a lot, and I also know that god will put an end to your pain eventually.
So, first of all you should stop hurting yourself, "Tzidi 3la rohek" like we say, stop thinking about the past, or what could've been if you finished your studies, that will only make you feel even worse
Accept what happened as something that god wants you to go through for a reason that only he knows, and you know that god only tests the people that he loves.
Like some of our friends here said, try to talk to your father or to get somebody to do it, maybe he will change his mind, and talk some sens into him, don't give up hope, and more important don't you EVER give up on your dream.
Read books, read stories online, watch movies...To make your english better, actually you know what? Write about your story, make a diary in enligsh, maybe one day it will be published as the story of one of the many algerian girls who suffer because of this kind of problems.
Your body is a prisonner in your house, but your mind isn't, so don't agonize your situation, I am in a vacation, I am at home 24/24 most of the days, and when we're in school, we're dying to be in hollidays so we can stay home, so just think of it as a really long vacation untill god gives you a way out (yfaraj rabi)
This is only temporary, you're not gonna be locked up in your house forever, god will not let you suffer untill the end of time, sooner or later something wonderfull will happen in your life that will make you forget about all these painfull years, just believe in god and believe in yoursel as well.
Whenever you feel like talking or getting something out of your chest, go ahead, I'll always be here for you <3
