Your all symptoms are related to anxiety
and allergy problems.
You should take good anti allergics such as combination of loratidine
good thing about that is it doesnot cause sedation and also use medicines related to anxiety such as alprazolam 0.5 mg at night daily for 02 weeks.
Initially also take a good antibiotic for throat symptoms such as azithromycin
for a period of 05 days.
