What do Ты do to feel better when Ты have a bad cold или flu.

Ok So a few days назад my cold started coming after sleeping over my Друзья house her cousin had a cold and she wanted to sleep in the same room with us.She's 6 years old and i think i caught it from her because she slept on the floor with us and she was coughing on me the whole time and my friend told me not to worry because she's almost better.It didn't look like it she even vomit on me a bit and i wanted to go Главная and душ but my friend сказал(-а) if i left she сказал(-а) that she was a afraid i wouldn't see her for a long time and i have a сердце for people.So i changed my clothes and stayed there because i felt bad.I Think i have the flu now because i have been feeling weak and i had a huge headache i even fainted.Please tell me if Ты think its the flu или just a cold.If Ты guys are sick i hope Ты feel better soon.
