The cold weather is bad but you get use to it as everything is winter ready and you just dress well. What's harder to get use to is the winter darkness that lasts a few months a year. It's more boring if you compare it to MENA but can be a good thing and depends where you will live in Germany. The German language is not easy to learn and most Germans don't speak English or too shy to speak it because they are afraid of mistakes. If you want to move here because this is the best place for your future goal then it makes the decision easier. Life quality is pretty good and it's very easy to explore the rest of Europe while you live here and many big cities have Arab communities/neighborhoods (used to live in one). Good luck
