This is hard for you I can imagine. Someone standing out, being different isn't easy to swallow for the crowd. It is not only about your hijab, but as the German population gets more and more divided over imigration policy your dress code puts oil into the flame. I have been abroad for 11 years and in spite of no external differences I always felt as foreigner. There must be something more.
Exactly, this time where middle east is burned, people come out the zone and try to get their life back, immigration is a trending topic. I think it is hard for every one to settle to the "new life". But I think education will make difference. If you think bigger, that for example German weapon industry takes profit if there is a war, than you should take some responsibilities toward the "consequences".
I very much appreciate especially your last sentence. It is really a shame and an example of Germany's hypocrisy to verbally preaching peace and selling weapons a mass at the same time.
