Translation of histérico

Thanks again for your time. I attached my avatar, it is very similar to the previous one. I have guided the development of the website, and I feel free to share my knowledge with others.
It is good if you have previously practiced only Spanish, which also shows that you are very good at other languages, and still can learn many things. I hope I'll learn it soon and practice.
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.
