I remember when I was diagnosed with diabetes, it was also the first week of the holidays and I spent a month in the hospital. It sucked! I'm sorry for you.
I'd like to spend the summer traveling somewhere and getting new experiences. Or I would really like to spend the summer as I did when I was a child in my Grandmother's village, taking care of animals, playing with friends and swimming in the lake. But I'm an adult now, so it's impossible.
Do you like books? The days in the hospital seemed less boring when I read an interesting book. Harry Potter was coming out in those years, and it was cool. I don't know what your generation is reading now.
