will my dad die?

I am really worried for my dad. he is 55 and has shown a fever all day today. i’m positive he has COVID. as soon as he told me he stayed home from work cause he had 100.8 degree fever I went and got tested for covid because I live with him. his fever has gotten worse throughout the day. he smokes and has drank his whole life. he’s getting tested tomorrow but i’m positive he has it and if he does, i’m terrified it will kill him. I don’t know what I would do without him in my life. i’m 20 and i’m scared it will kill me if I have it. i am showing no symptoms as of now but i am close with my dad and have been in contact with him before he had a fever. since then i have been keeping my distance and washing my hands. idk I just am freaking out and I really just need someone to calm me down. i can’t stop crying.
