In your hospitals they don't allow electronic devices? That's terrible!! They did in mine and while I was in the hospital (for 2 weeks as well) I was able to watch movies, and read books (I went through countless books) Hospitals can be very boring but the good thing is that they are there to help you get better. I would have died if I wasn't admitted. What you say about the cockroach is true. Sometimes the little things you think of as bad turn out to be good things. For me it was passing out while buying food. If I didn't go food shopping that night, my heart would have stopped and I would have died. I couldn't draw in the hospital either because of the IVs in my hands and arms. (I have a blood disease) I know what it's like to feel a little lonely too. My family is in a different country so it was definitely a little lonely. Know that your fans are here for you no matter what!
Keep fighting! You'll get better and when you do you'll be back on track making marvelous, wonderful, awesome artwork like always!! I wish I could send you something to read too but I don't have anything in Thai (most of my manga is in Japanese and English) Take care of yourself! Stay positive.
