Sore throat- super anxious

Okay so I have bad health anxiety and I haven’t been able to sleep all night. A few days ago I woke up with a small sore throat, brushed it off cause I sleep with a fan pointing me so I assumed it was because of that. A few days have passed and it’s very painful. I do have quite a bit of mucus in my throat and I’m assuming it’s because of that. I have no fever, no cough, no shortness of breath. I’m just super paranoid and feel tired but can’t sleep. Any advice or thoughts on what it could be? And do I let it pass on it’s own?
