Any good websites that could help me learn German?

Ich bin lernen Deutsch jetzt. And my inspiration? TOKIO HOTEL <3. But, German being one of the most difficult languages to learn, I am having grammar and pronounciation troubles. I reaaaally want to learn it now while I'm 13 so (even though I'll sound bad) I won't sound as bad as a 50 year-old man trying to speak Spanish. So, people, I leave my polyglot-future in your hands. u_____u
