Salam alikum, you seem to be very touched indeed, wuold like to give you some advices, and allah hopefully gives you guidance. I am alone sister - in my whole town there is no muslim at all - I mean stable inhabitant. Despite that I wear hijab outside and also at my workplace. SOME poeple in my surrounding also tried to treat me way you describe and they always do, but think about it. It is not your fault that they have weak character, that they try to put you in position of second class., that they humiliate others... You have nothing to do with that. Hijab is one of your protection and if you give up of hijab, you very easily fall into society of disbelievers, they will invite you - no doubt, but you might loose their respect - and that will happen most certainly. The worse will be that you might not recognize it. w alikum assalam
