Have you tried participating in Meetup type events organized by meetup groups(meetup dot com is the name of the site) or Facebook groups where there's expats who join in? I don't know, something hobbies based or just for socializing in English, for both locals and expats. There's some groups like that here and they're good for meeting new people.

I know it's not very easy to get to Europe and stay here, as a citizen from an African and/or arabic country, but I think you do have a good chance to get here via some university course of whichever type, Phd or another Masters or something. If you don't speak another language apart from English, you should still look all over Europe, there's English speaking Masters and Phd programs in other countries as well and you could also try learning German. Seriously, if you like foreign languages and would not mind trying to learn another, I suggest German because Germany and Austria are great to study in and Germany also offers the possibility of taking month long German classes in preparation for starting a Masters or Phd course.
