Studying Abroad in Estonia?

I'm wanting to study abroad in Estonia and I'm wondering if anyone has any advice. I know I need to be able to pay for insurance, the flight, boarding, classes, a residence permit, a student VISA and all the other things like food/utilities/etc. They offer semester programs, but I am told by many people that a semester isn't the best because as soon as you're used to everything, you're already days away from your plane trip home. My question is that is there any creditable places that offer student loans? The problem for me is that my parents will not cosign on anything for me as they're completely against me going overseas. I'm hesitant on asking for federal loans because if all goes well, I would definitely consider moving there. I know it's easier said than done, but I'm definitely keeping my mind open to the idea. I'm completely going into this blindly in terms of knowing what else I need to do so any help would be greatly appreciated! Thank you!
