Translation of problem-free in German

So by age twelve, I had decided that I wanted to learn English and I was studying for the United States TOEFL at age twenty. Being bilingual practically from birth, makes speaking languages very easy for me.
Anyway, there are a lot of people on board and I no matter how high the waves may be, I always suffer from nausea or seasickness. I have not been on a small boat before. I will have to vomit.
I'm still doing many mistakes. I will gladly assist you, with the Spanish language. I am learning English. Can you help me there too? I would be glad if you could write me soon.
