Happy.. Day??

I don't did not go to school today because I'm ill. (You need, did not in this sentence for past tense. Do is present tense. Also you do not need the period after today. Because connects the two sentences.)

Though I have a lot of time to relax, I really feel bad and tired.
I think I can't get free or healthy at the same time.

You did very well. I am sorry you are ill. You will get better soon.
