On the EU ref

I don't know why I ever felt like I could plan the future. The truth is no matter how hard you try to control everything, you just can't. No one has ever managed to do it, so I don't know why I ever thought I could. I can't predict anything, not even where I'll be living in the next few years, at least not any more.
I'm not going to talk about Great Britain leaving the EU from a political stance. This is not the point. The point is that opportunities have been taken away from brits and EU citizens alike and that is a fact that is going to dramatically influence my life. The UK is my home as much as France is. I guess now this sentence will have to change to: the UK was my home as much as France was. I've spent nearly 8 years of my life in England and by the end of my studies, I'll have spent 10 years in the UK. That's 5 times longer than I've lived in France.
I'm getting my education here, I spent my childhood here and now I know I won't be able to live my professional life here. Some might argue that it's a good thing because that means I won't be stealing anyone's job. Fair enough... except it's not. My dream in life is to be a business owner, for that become a reality I need to create a business, hire people and lift my ideas to the top. In the worst case scenario, I'd be a competitor on a specific market, creating tension and lowering the cost of things. I'd still be paying taxes, spending my money in England and contributing to the country. However, that won't be the case because soon, I won't be able to legitimately live in the UK for an indefinite amount of time. My french passport will not grant me access to the place I've called home longer than any of the other 3 countries I've lived in. I don't have many roots but the few I have are here, and I'm not wanted here.
So where do I go from now?
