This is my first text since I was in High School. It will be a calamity but I need to improve my knowledge. I think that my writing is bad, but I don´t care because I think that everybody can learn from their mistakes. For me it is very difficult to think in English because I have learned German since I was five years old.

I want to learn English and German, but I need more time.

Very good! :) Perhaps try to use simpler vocabulary to build your confidence as you have just started - some of that was very complicated for a beginner.

Reconsider the word 'calamity' as it is very dated - 'disaster' is more commonly used.
