How to study without having money
In your circumstances, your best bet is likely to study in your home country. Many EU countries have stipends or student loan schemes targeted at qualifying local students that could otherwise not afford higher education. If you are willing to work next to studying, the world is basically your oyster anyway - many/most institutions in Europe allow students to work next to their studies even if the program is nominally full-time (of course the university does not look for a job for you, that would have to be your responsibility).

In your circumstances, moving to a different country to study will be a lot more challenging. Student loan schemes and stipends are often not available to foreign students, and funded study places basically only exist for the PhD level.
