I know my user name sounds...well...not muslim, but its not my real name, i'm muslim. My family is not very religious but i do have relatives that are Muslim families... And I'm also a 15 year old girl too. I'm not sure which part of the world you live in but i can see how difficult that may be...Feeling like you need to hide things from parents because you can't do certain things and you're scared to tell them. What one of my cousins did was actually sat down with her parents and asked her parents wat their expectations of her were and wat they thought she would be allowed to do. After they told her, she began to explain some of the things she wanted to change and some things she thought she should be entitled to do as a free human being on this earth...a lot of this has to do with confidence and being able to stand up for yourself ...This obviously may not be easy because most parents THINK they don't need to hear a second opinion and feel they know what's best for their kid...and sometimes, it's not always the best thing... Try that approach and see what happens..
As for your brothers, how old are they? And if they are physically or verbally hurting you, have you tried talking to a school counsellor? Not sure if you're school may have one but if you do, i know i was scared at first to talk to mine, but it really helped. I'm afraid for you, and what your brothers could do to you eventually. They may not mean it intentially but it really needs to stop. You are a human being and deserve respect and being physically punished for nothing is a VIOLATION. It doesn't matter if the person is related to you or whatever...It hurts, and it shouldnt be done to you.
And with the pills and cutting...I know, I've been there, and it sucks. But just remember it's not worth it...don't inflict more pain on yourself because you can't stop them inflicting pain on you...Remind yourself every now and then that you are important in this world and have to be treated well and be loved to make it far...And remind youself that you ARE loved and are of very good use to this world...
Try talking to a cousellor if you can and see if you can work out these problem...you may be surprised at how things can really work for you. Keep posting if you have anymore troubles, we're here for you :) .
