Sorry fairly long, so for those of you who want a TLDR version:
Am European and worried whether March and the repercussions of Brexit will lead to aggression and violence against people like me.
So I am originally from a European country. Moved here on a whim a month after finishing high school (twelve years ago) and never left as quickly found that my friends, studies, work, everything I knew was here and going back to my home country would actually feel like 'immigrating' given that I have never applied for a job there, never rented a flat/bought a house, never even paid taxes. I work in a professional career and while I could work there (or most places really) pretty easily it would be rather daunting as my entire professional vocabulary is in English if that makes sense at all. Never thought I would consider moving back.
BUT
The whole Brexit vote really shook me as had been living in London and was blissfully unaware of the hatred towards 'migrants' the rest of the UK had apparently been harbouring. I now live outside of London, in an area which will likely be severely economically affected by Brexit (the main employer in the area has announced that in the case of a no-deal scenario they will be moving the company as it would be unsustainable here). I am worried that what until now have been remarks off 'well it's not people like YOU that are the problem...' 
, will turn to actual aggression or violence by these people as I cannot see them blaming themselves when the economy goes up in flames.
At least objectively my birth country has a much higher quality of life, but I don't want to leave my home, my job, my friends and my life here. However, I am actually starting to get a bit scared of these people and of the possible repercussions for me and my family. (I have a very mild, but occasionally detectable accent and a very obviously European surname).
