seems to me that you don't hate school much, you still went to school.
however, i must point out that playing in the rain on a cold day = suicide.
if you want to get better, don't get sick. Playing in the rain on a cold day is the perfect way to get sick. Why should you listen to me? I'm studying to be a doctor, and my advice to you is stop playing in the rain on a cold day.
You can't just play soccer and thats it, there's other things in life besides soccer. you want to look after your body, and antibiotics and being out of school for a wk coz u'r sick (you must be really sick) isn't doing your body any good.
my advice on how to deal with ur parents.
go up to them and say "hey mum, thanks for caring about me so much. I know i got sick two weeks in a roll, that must have freaked you out heaps. I promise ill look after my body better. I'm doing pretty well in school too, i hope i can get back to my school work as soon as possible"
having said that, if you don't study, it'll blow and ur parents won't believe you. When you show your parents you're studying, naturally, they'll go "hey peps, you can go play soccer
and then you go play soccer, but not in the rain on a cold day.
