I have clogged right ear, sounds and claustrophobia are driving me to feel mental! What really works for most people?

Having gone to my doctor for antibiotic and ear drops, then to ENT doctor for wax removal and more ear drops, they say it will get better. It has been almost 2 months!! Crackling noises, stuffed up feeling, feels like pressure behind the ear drum. It started to deminish a little, then it all comes back again. I have severe claustrophoba fear, I can’t get away from this! I have tried SudaFed, Nedi-pot, antihistamine, chewing gum, yawning, hot steam, hot tea. I have anxiety that this will never get better!
