I would say that if you really want to fly, you live only once and go for it.
You are young and smart. ...GO FOR IT.
Time is on you side, used it.
What does it take to learn German?, get your backpack, take the first flight to Germany enroll in Goethe Institute, do an intensive course, live there for 6 or 12 months while you work to cover your expenses and then try LH... if LH does not work, what did you losse?, only 12 month of your life, what would you learn??? a new languaje, a "living abroad" experience and if you missed LH training, you will know that at least you tried it.
Then, you can return, and start again, one year when you are young it is not that much when you are over 25.
FYI, chances to get into LH are 7%, low, but focuse on this 7 % and be positive, if you missed, you will never regret beacause you tried it (Sounds like a "Nike" commercial?? ...Just do it).
That is my advice. Anyway, i wish you good luck.
