Translation of verrückter

I work as an actor in the theater. I have studied English for seven years, French and Spanish for two years. Well, my level of Spanish is too low to have a good conversation, but I understand it.
The easiest way of writing sentences in Spanish and English is to communicate with other people by email or by chat. I found the different time forms quite in Spanish very confusing at the beginning and it was the most difficult part.
My company is a consulting firm for IT systems for banks and insurance companies. I work with system analysers and bank employees. It is a big challenge, technically and commercially. I love it.
