Help me become an exchange student

Hello everyone! I'm writing this hoping someone will actually read it. So, let me introduce myself. I'm Emili from a small country of Croatia. I'm 20 years and studying Management of Sustainable Development and Tourism. This year I got a chance to move to wonderful Madrid to study there for 6 months. I've been thinking about it for so long. This way I could practice English since I'll be studying in English and improve my Spanish. Also, Spain is a country full of tourists and studying tourism in a country that is super popular for tourism seems like the right thing to do. Also, last year I was studying like crazy just to be able to get this opportunity. I'm also planning to have 10 more exams in the next month ( which I should do in February like everyone else) just to be able to move in January. I think you can see how important this is for me. It was my dream and made me extremely happy. The only problem is that I'm super anxious now thinking that it might not be as beautiful experience since everything is a lot more expensive in Spain and in my county. So, even tho I've been saving and got a scholarship it is not enough to even rent a room in a students' flat let alone be able to buy myself food or anything else. At first, I didn't want to ask for help but I've been looking for flats for 5 days and haven't found any that isn't too far and that I actually have enough money for it.
