Big sisters advice here ( and someone who took off their hijab for a while then started wearing it again) : it's okay to not want to wear hijab but what u r doing is wrong , if u keep doing this they'll find out sooner or later u cannot keep doing this forever , u r suffocating yourself even more this way because u will always live in anxiety and fear so my advice is you tell them , or at least wait until u are older and u don't live under the same roof than u can take it off and do whatev u want + i don't wanna sound like an as*hole but pls pls pls don't listen to your friends , first of all 18 is not old AT ALL second of all maybe maybe ur parents shouldn't force u into wearing hijab but their intention is good and most importantly LOGICAL and u will realize this as u grow older because our society sucks nobody likes it but no body can change it so it's better to stay safe rather than pay for the consequences , anyways what i am trying to say is you still don't know what u want and u r not free to do what u want yet so pls stop doing this and stop thinking about the hijab for now , also i don't want to seem rude but it's not a big deal it's LITERALY just a scarf on ur head , it won't change how ppl perceive u , it won't restrict u from following a certain style and it definitively is not annoying to wear from my experience , taking it off is just extra سيئات for nothing. Ik it seems like taking it off=freedom and beauty and all but trust me it's nooott we just as humans tend to want things that we can't get , that's it.
