You've asked about me, I'm still working. This week has been really tiring because I'm trying to get my driver's license and I have an exam on Saturday, I look forward to it. I don't know what's going to happen, I haven't studied enough, we'll see... I'm not sure whether I'll pass, but I have to do my best, my dear.
mucho fatigosa ---> muy cansadora (es más apropiada en este caso)
esto sábado ---> este sábado
estoy ansioso por eso ---> estoy ansioso (es suficiente, no precisa decir "por eso" )
suficientemente ---> lo suficiente
