Translation of happier in Spanish

Well why are you doing that to yourself? That is very hard. You can easily write in another language, if you prefer, because I speak many languages and I can understand many more. I only have problems with writing.
I'm quite tired too by now. So, if it doesn't work just drop me an email and I'll see it first thing in the morning. I wanted to add new words to the dictionary however the other issues kept me more busy than I have imagined.
So this is my last week here in Germany, then it's back to Italy. I'm not sure if I will return soon. But I am longing for friends and family. I will certainly return one day, that is sure.
