please give advice or just reassurance 😭

i have a sore throat, a small cough, and a headache. probably just a cold. it’s almost 7am for me and i’ve not been able to sleep. i keep swallowing every few seconds. it hurts but i can’t not do it. idk what’s happening, every time i lay down to sleep i feel like i need to swallow more and then i get anxious that im gonna be sick. i’m sitting up in bed, exhausted right now. ik i need sleep to get better but im scared. literally any advice or something would be helpful rn. please! i dont even feel n* just like i keep having to swallow for some reason.
