前面是英文，后面是中文。I got a fever today.And l am in blue for nothing.l was never like this before when l was ill,unless there was something depressing.But nothing depresses me today.No matter what the reason is,l must make myself happy.To myself happy,l decide to listen to music that l love.Gradually,l become in a good mood.when facing this situation,how do you deal with it?
Fang, a tiny suggestion here: You may want to leave a space between your sentences. Yes, it is stylistic, but your English well enough for you pay attention to it, right?
a better way to phrase having "blues" would be, "I have the blues." or "I'm feeling blue." Also don't start sentences with "and" or "but".
To answer your question, I play my guitar I find that very relaxing.
