Chronic granular pharyngitis. Me

I  was  diagnosed with  granular pharyngitis and allergic rhinitis since last year during the month of August 2020 ,I took all antibiotics and antihistamines as prescribed by the doctors but they didn't worked that much , the medication results were temporary and I didn't see any adverse improvement in my situation .Changed three ENT doctors during the duration of this one year . Now it has been a year in july 2021 but now also suffering from prolonged symptoms of sore,painful and itchy throat , sometimes runny nose with frequent sneezing also sometimes difficulty in speaking with mild pain in throat. Under torch light using mirror I can see lymph follicles at posterior wall of the throat and inflammed tonsils . I feel depressed and stressed about my situation need permanent treatment from this chronic disorder , now my life is solely dependent on taking antihistamines pill everyday. PLEASE HELP ME 😫😫🙏
