求翻译：I arrived back home about 1:00am this morning after a good flight from Sanya to Shanghai. I am getting ready to go for my medical exam this morning at 8:00am for my work permit. I catch a 5:30pm flight back to Sanya this evening, arriving in Sanya around 8:00pm. My work collegue had the flu last week and was off work a few days. I now have what he had so I'm going to stop at the pharmacy today and get some medication. I promise I will be careful to take care of myself though and rest when I get back to Sanya.是什么意思？
