Dear customers, I want to explain why I work rather slowly. I now feel very bad physically, I have severe headaches that can last for several days in a row, so I can sleep all day, but I'm not getting better, these pains are so strong that I can not even get up. Also, due to the fact that I constantly study at the University, I did not have time to visit doctors and my health is not very good, now I go to doctors and do expensive examinations, and it takes time. I hope for your understanding, I try my best!
