I'm sick and scared

37,5 C!

My nose has been running on and off for past few days, my throat is hurting.... And now I learn that my temperature is 37,5... And what if I've had it for few days?

I can't even do anything. Every time I go outside I get cold. I try to stay warm, but it doesn't ever work...

I've read that it's not as bad as far it's not 38 C, but I'm scared 😭

What do I do?
