Translation of paranoid in Spanish

I usually charge 15 dollars per hour, but I don't care very much for the hourly system. I can also help with corrections and suggestions, but only if the original text is a serious translation and not an automatic one.
I want to study either computer science or do an MBA. I love to programm and I am doing it a lot, although I am very impatient sometimes. I also like math, but I hate writting long letters.
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.
