Help me please. It´s really important for me :D

Today was a difficult day, because I went to the hospital with my mom and the doctor told us about her illness. Since I started working at a call center, my salary is better. That´s why I could  how I was able to pay for the treatment. My mom will have an appointment with the doctor once a month. I am worried for about this situation because it is the first time that she has had a problem with her health. My mom works in a place where she has to do so much a lot of exercise for many hours. The doctor wrote that she must not do exercise for a long time, but her boss is very strict about this. One of the my major  biggest problems is I have to work for 8 hours to pay for my expenses and I study at the university in the morning. and The most difficult part is I don´t have enough time to take care of my mom. The only thing I can do is improving improve my English quicker quickly and find an opportunity in another country to have enough money and have time to take care my mom.
